1993 Honda Accord

What would make my 1993 Honda Accord spark plug smell like diesel fuel?


Contaminated fuel. This is more common than you would expect. The same delivery trucks are sometimes used to transport different grades of fuel. Under normal operating procedures the tanks are flushed after each haul. This helps prevent contamination of diesel and regular grade fuels. When this step gets over looked there can be upwards of a 100 gallons being mixed in the next load.

When your fuel is contaminated the engine may struggle and have performance issues. The engine may “PING” on heavy acceleration. Though in the short term no damage should occur but if not corrected severe internal engine damage will. Feel free to drive that tank out and fill up at a different fueling station the go around. For large fuel tanks an Octane boost may be used to prevent engine ping.

Nissan Altima

I need to repair the blend or mode motor and door assembly. I can’t get defrost or floor vent to open. The air conditioning only blows at me. How do I reach the blend door assembly?


You will need to remove the instrument cluster from the dash panel(see video). Then you will need to remove the BCM that is located behind the instrument cluster.

Chrysler Town and Country

Engine light stays on. Mechanic’s scope indicated a code and changed the Catalytic Converter and one Oxygen Sensor. Shortly after the engine light came on again. He changed the second Oxygen Sensor. Light came on again Both times he used his meter, the code said the problem was with the Sensor. Any suggestions for what I should check next? Could the problem be electrical (a short or faulty wire harness)?


I am guessing as to what the actual code is as you did not provide it. If the code is different please indicate it by responding in the comments.

Chrysler Code P0420

Description: Catalyst System Efficiency Below Threshold Bank 1

Probable Causes:

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. HO2S sensor contamination/damaged
  7. Exhaust leaks or restrictions
  8. Catalytic converter damage

2001 Chevy Monte Carlo

Why is the turn signals blinking fast at the front of the car but the rear lights do not come on?


This is normal for when there is a bulb failure. You should also notice the turn signal indicator on the dash flashing fast as well. Replacing the bulb that does not illuminate should fix the issue.

Turn Signal Bulb Replacement

  • Open the hood.
  • Remove the radiator air baffle.
  • Apply light pressure to the headlamp lens to hold the headlamp in place while removing the retainers.
  • Lift up the headlamp retainers to release the headlamp from the upper fascia support.
  • Remove the headlamp from the slots in the upper fascia support.
  • Replace bulb

Turn Signal Lights

The TURN SIGNAL fuse in the LH I/P fuse block supplies ignition positive voltage to the hazard and turn signal lamp flasher assembly. The HAZ SW fuse in the RH I/P accessory wiring junction block also supplies battery positive voltage to the hazard and turn signal lamp flasher assembly. The turn signal lamps may activate only when the ignition switch is in the ON or ACCY position.

When the turn signal switch is placed in either the left or right position, current flows from the flasher module’s output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or the right turn signals and their instrument cluster (IPC) indicator. When you press the hazard switch, all the turn signal lamps and both of the IPC turn signal indicators will flash. The hazard and turn signal lamp flasher assembly is grounded at G201. The front turn signals are grounded at G101 and the rear turn signals are grounded at G302.

Dodge Ram 1500

radio sound goes in and out about every 20 seconds


Quite a bit of noise about this issue. From some of the posts I have read, the FIX was replacing the RADIO(not the Amp).

  1. Just as a quick try, Try disconnecting your negative battery post for about 60 seconds. Sometimes(but not always) this will clear an electrical glitch. It can’t hurt, and in fact, will give you the benefit of re-setting the PCM(like the Fuse 2 removal). Second thing I would check would be to plug connection in the back of the radio. Hope one of these two simple things may help you.
  2. Mine was fixed at the dealer. First they thought it was the amp which they replaced and still gave the same symptoms with everything working, just no sound. Then they replaced the radio and that solved the issue. So I ended up a new amp and a new radio. No problems since then.

2006 Toyota Sequoia

New rack and pinion

Well I put a new rack and pinion in my 2006 Toyota Sequoia but had a issue. I didn’t tighten the drive shaft screw at bottom. But did tighten the two on top I was going to back to tht after I screwed the nozzles in I got the one small looking nozzle but the other would not tighten for nothing it didn’t look stripped it looked fine anyway the sun was going down and I had to get ready for work so I thought to my self I could tighten the one screw on driveshaft and put the nozzle in with my tires on ground anyway.

I put my tires on and took it off the jack and stands and started working on the nozzle which I couldn’t get to tighten but as I’m looking up I see the driveshaft screws are turned the opposite direction, and even tho I didn’t get the nozzle on all the way I just wanted to try to start my truck it would not turn over my truck always turns over all the lights lit the dash and made a weird sound but not even close to starting
You
Do u think there’s a problem tht my screws for my driveshaft are turned the opposite way in which I can’t reach is the reason my truck won’t start or the nozzle not in right or both


Would not turn over

No. I think your battery drained while you were working on it. This is VERY common. Fully charge the battery and the vehicle should start right up as normal.

Your lights and radio will work fine with a weak battery as they require as little as 5 to 15 amps to operate. However a starter requires upwards of 200 amps to operate correctly.

I have a Toyota Auris (57 plate) which has started making a really strange noise. I have uploaded some dash cam footage of the noise here:

It is quite a loud sawing/grinding noise that seems to occur when I drive around 40mph or more. The noise generally comes and goes when I am over this speed but what I did notice is;

– The noise stops when I apply the brake, please see from 10 seconds on-wards and you’ll hear the noise goes away

– Also the noise tone changes when I steer to the left to a sharper but quieter noise

It sounds like the noise is coming from the engine but it is quite hard to tell. My engine makes normal noises when I am stationary. The noise is really annoying to hear when I am driving however and I want to get it fixed. Does anyone know:

1) Why is my car making that noise?

2) What would need repairing to get rid of the noise

3) How much could that set me back if I get it fixed?

Many Thanks,

James


Loud sawing/grinding noise

In most cases when the noise gets quieter when you apply the brakes, the issue is with the brakes. However you also said the noise changes pitch when turning from left to right. This is an indication of a hub bearing going out. When the hub bearings start to fail they can also cause premature wear on the brake pads.

Therefore disassembly and inspection will be required to determine the exact cause and cost.

2005 Chevy Impala

I’ve taken my car to a million mechanics (including the dealership) and there’s some electrical problem causing my low beams not to work. I adjusted my high beams so they point as low as possible. Is this ok? Will I still blind people?


Of course the best course of action would be to fix the issue. (most common cause would be the Multi-function switch) I would think any headlights are better than getting a ticket for driving without them. I’m sure it won’t take to many test drives at night to find out what oncoming drivers think about your headlight adjustment.

As far as blinding people with your high beams, I can understand your concerns.

Headlight Aiming

Headlight aim has been preset at the factory and should need no further adjustment.

However, if your vehicle is damaged in an accident, the headlight aim may be affected. Aim adjustment to the low-beam headlights may be necessary if it is difficult to see the lane markers (for horizontal aim), or if oncoming drivers flash their high-beam headlamps at you (for vertical aim).

If you believe your headlights need to be re-aimed, it is recommend that you take the vehicle to your dealer for service.
