Since having NEW rear brake pads, & shocks, my right rear wheel makes a metal to metal sound when I start to stopping. Did not do it BEFORE new brakes. Took it back, all they did was spray dust off wheel. Still happening on only one side.

Take it back again and politely suggest they allow a mechanic or themselves to take a ride with you. This way you can replicate the noise you are experiencing. It shouldn’t make the noise. Occasionally in the rain or wet weather or directly after it may make a noise or two the first couple of times but should fade after that.

Taking it apart and looking at it is what will be required. Also if you did not replace the brake rotors at the same time, it would be normal for the brakes to make some unwanted noise. This unwanted noise should quite after the NEW flat surface of the brake pads mate with the old GROOVED surface of the rotors.

I believe my crankshaft position sensor is bad because the wires that went to it were burnt and open and I also do not know where these wires lead. if you can help please let me know.

Sounds like you have your hands full with this one. It certainly couldn’t hurt to replace the sensor while your in there repairing the burnt wiring. I have provided a couple of wiring diagrams to help assist you in fixing your problem.

Honda Accord

Hello, I am a 20 year old young man looking for a first car. I am torn between a 2008 Honda Accord Sedan Manual Transmission with 133k miles on it for $2500 or a 2012 Mazda 6 automatic transmission with 108k miles, needs a wheel bearing and there is a small crack in the back bumper for $2600. Both cars are from private sellers. What would you recommend? Thank you so much!

Condition and comfort would play a big role in it for me personally. At 20 years of age you will be spending quite a bit of time in the front seat. But lets suppose they both are equally as clean and comfortable as the other. The Mazda needs a wheel bearing, that is 2 hours book time labor plus parts.

So now you have a 2012 Mazda 6 with $2600 + $50 for the hub bearing, we will assume you replaced the hub bearing yourself, vs. a 2008 Honda Accord for $2500. We will go on to assume that the body on both are pristine. So lets look at some Pros and Cons:

  • Fuel Mileage 22/31 – same for both
  • Passenger Air Bag Safety Recall 0717A – 2012 Mazda 6
  • Multiple Technical Service Bulletins related to the transmission on the 2012 Mazda 6
  • Multiple Front Air Bag Safety Recalls – 2008 Honda Accord
  • Multiple Technical Service Bulletins related to the Windshield Wiper Motor not working(RECALL) – 2008 Honda Accord

From the looks of things they are both about in the same shape with the exception of the Mazda transmission TSB vs the Honda windshield wiper motor. As far as that goes the wiper motor is bound to be a less expensive fix if it came to it.

The Car I Recommend

They are both about the same. Maintenance costs are also about the same. The Honda tends to have a more reliable reputation. The Honda however is a stick shift and the Mazda is an automatic. In my 20’s I wouldn’t have cared and may have even preferred a stick shift. But as I have gotten older I prefer an automatic. So I would chose the Mazda for myself based on that. As for you still being in your 20’s, I recommend you pick the one that is comfortable and fun to drive.

Ford F-150

My truck starts fine. When in park to warm up after a few months it revs up then low high then low and shuts off when put in gear I have to sometimes give gas quick!! When accelerating it feels like it don’t want to get up go. Other then that it drives fine.

Sounds like a possible vacuum leak or a faulty IAC Valve. The IAC valve or Idle Air Control Valve is a component that can fail and not cause the check engine light to come on in all cases. There may be helpful trouble codes stored if the check engine light is illuminated.

Cadillac Fleetwood

I would like to get the ECM wiring diagram because I purchase a new ECM and i transferred the Prom to the new ECM but the ECM still not activating pin 85 of the fuel pump relay.

I would like to note that the relay will only activate for 2 seconds. The Fuel Pump Relay is energized for 2 seconds after the ignition switch is turned to “RUN” or as long as the ECM senses ignition pulses. So if the battery voltage is there for the initial 2 seconds and then is lost, this is normal. You may need to look at why the ECM is not getting engine pulse signal. Check the fuses and wiring if you are not getting battery voltage for the initial 2 seconds.

I have been working on a blown head gasket replacement for this engine. (Mysteriously the head & block were not warped – so I replaced thermostat & water pump hoping that an overheat caused it to blow)

I have gotten to the rebuild & put the cams back in. When I went to turn the engine over to check for interference with the pistons & valves it does get stuck at one point. The last idiot tried to do some work on the engine & had removed the crank pulley. It seems to have all gone back together with the timing marks on the cam gears matching the chain marks.

I have no idea how to move on. Any thoughts?

You stated that something is getting stuck. This sounds like something is hitting internally. Taking it back apart would be the next step.I am thinking you may need to check for a bent valve or just re-check timing.

Make sure to follow the rule of turning the engine over several times to check your timing is good before assembling the rest of the engine.

Timing Chain, Replace

Caution: With timing chain removed, avoid turning camshaft or crankshaft. If movement is required, exercise extreme caution to avoid valve damage caused by piston contact.
Caution: It will be required to recover A/C refrigerant charge. Refrigerant recycling and service equipment for R-134a refrigerant will be required.

cable connector

In this photo of the connection of the transmission cable to the automatic shift. I see no clips, screws, or other mechanical fasteners. Visibly, there is just a pin and surrounded by a busing. I need to remove it in order to remove floor console in order to remove the airbag module. I am afraid I will damage if I just pull the connector off! What should I do?

I like to use a flat blade screwdriver and slide it underneath. Then pry it gently off. Post below the year, make and model along with the engine size and I might be able to find more on this specific vehicle.

2004 Dodge Ram 1500

I have got a code p0430. I changed the spark plugs and coils along with bank1 sensor1 O2 Sensor. The Code is still appearing. Next we are fixing to remove the catalytic converter on passenger side.  Asking your opinion?

First after looking at the code and its description (below) I see that Bank 2 is the problem side. I also see that you replaced an O2 sensor on Bank 1. Was that in an attempt to clear this code or was that for a different code issue? I think before you replace anything else you might follow the diagnostic testing procedure below. This should help guide you in the right direction.

Dodge Code P0430

Code P0430 Description

Catalyst Efficiency Below Threshold Bank 2

Code P0430 Diagnostic Testing

1. Active DTC – Diagnostic Trouble Code

Note: A new rear O2 Sensor along with an aging front O2 Sensor may cause the DTC to set. Review the repair history of the vehicle before continuing.

Note: If an O2 Sensor DTC set along with the Catalytic Converter Efficiency DTC diagnose the O2 Sensor DTC before continuing.

Note: Check for contaminants that may have damaged the O2 Sensor and Catalytic Converter: contaminated fuel, unapproved silicone, oil and coolant, repair as necessary.

Ignition on, engine not running.
With a scan tool, read DTC’s.

Is the DTC active at this time?

YES -> Go To 2

NO ->

  • Refer to the INTERMITTENT CONDITION Diagnostic Procedure
2. Visually Inspect Catalytic Converter

Inspect the Catalytic Converter for the following damage.
Damaged Catalytic Converter, dents or holes.
Severe discoloration caused by overheating the Catalytic Converter.
Catalytic Converter broken internally.
Inspect both ends of the converter, inlet and outlet.
Leaking Catalytic Converter

Were any problems found?


  • Replace the Catalytic Converter. Repair the condition that may have caused the failure.

NO-> Go To 3

3. Exhaust Leak

Start the engine.
Inspect the exhaust for leaks between the engine and 2/1 O2 Sensor.
Inspect the exhaust for leaks between the engine and the 2/2 O2 Sensor.
Turn the ignition off.
If a leak is heard but unable to be located, it may be necessary to use a special Miller Tool #8404A Evaporative Leak Detector (EELD) or equivilant on the exhaust system to find the leaks.

Connect the SMOKE supply tip (black hose) to the exhaust cone adapter (if equipped) and place it into the tail pipe.
Set the smoke/air control switch to SMOKE
Press the remote smoke/air start button.
While holding the remote smoke/air start button, use the white light (#8404-CLL) to follow the EVAP system path, and look for the source of the leak indicated by exiting smoke.
The exiting smoke deposits a residual fluid that is either bright green or bright yellow in color when viewed with a UV light.
Be sure to check the exhaust manifold to cylinder head connection for leaks.

Are there any exhaust leaks?

YES ->

  • Repair or replace the leaking exhaust parts as necessary.

NO -> Go To 4

4. Engine Mechanical

Check the exhaust for excessive smoke caused by an internal problem in the engine.

Is an engine mechanical condition present?

YES ->

  • Repair the engine mechanical condition as necessary.

NO -> Go To 5

5. Aging O2 Sensor

A new rear O2 Sensor along with an aging sensor may cause the DTC to set.
Review the vehicles repair history.

Has the rear O2 Sensor been replaced without replacing the front O2 Sensor?

YES ->

  • Replace the 2/1 O2 Sensor as necessary.

No -> Go To 6

6. Catalytic Converter

If there are no possible causes remaining, view repair.


  • Replace Catalytic Converter

Chevy Cruze

Overheating/ boiling into reservoir, Already replaced thermostat, both radiator hoses, both temp sensors, coolant manifold. Within 5 miles of driving it will overheat, Burped air out. Replaced water pump last year. Reservoir tank/cap? Head gasket? Ideas?

You have obviously be at it with this one for a while. Lots of good parts thrown at it and still no better off. So lets try a different approach. Lets do some testing.

Perform a cooling system pressure test and an engine cylinder compression test. The cooling system pressure test will allow you to confirm if there are any leaks present, internal or external. The engine compression test will show if there is a blown head gasket.

Another quick test would be to install the cooling system pressure tester and start the engine. You know you have some internal engine issues if you start to see the pressure build way over the manufacturers pressure limit posted on the radiator cap. (15-17 psi)
