Ford TaurusI have a v6 2007 Taurus with engine light on . Engine code reads bad cat converter and i need it fixed for emissions however car runs great. question is , if i get a universal catalytic converter to save a lot of money will the light go off or does it have to be a manufacture cat converter specific to my car


RESPONSE

You can opt for the universal converter but at a cost. The effectiveness of the universal will not be the same as the direct fit. Also the old converter will need to be removed and the universal converter welded in its place. This means extra time and labor which is usually a wash. I recommend using the direct fit catalytic converter when replacing it.

Ford ExplorerMy car will start when it is cold but once I drive, even a short distance, it will not start again until it is completely cool again. I had it in a shop where the guy changed the fuel pump, sending unit, fuel regulator, the air flow thing, sorry don’t know what it is called. Nothing changed and he just kept wanting to working on my car. I just could not keep paying this guy when my car still does the same thing it always did. He also changed something he said would be in place of a cap and rotor because my car is fuel injected. I don’t remember the name of that part either. I feel like he was taking advantage of me because I am female. Sorry but that is how I felt. Help please. I have to figure this out.


RESPONSE

Most likely cause of this issue would be the ignition control module. When an ignition module is failing it will act just like you described. It sounds like the shop you took it to is just throwing parts at it with the hopes it fixes it. You may want to take it to a different shop and start from scratch. They may want to diagnose the issue and run a few tests but better than paying for parts you do not need.

What you need the shop to do

You will want to have the shop test for what the engine is not getting when it will not restart. This will help guide them in the right direction. An engine needs four things to run and without one of them it will not run.

  1. Spark
  2. Fuel – Fuel Pressure and Fuel Injector Pulse(it sprays fuel)
  3. Compression
  4. Timing

We can rule out compression and timing as we know it does run for a short time. And since it starts up after it cools down it is less common for it to be a fuel related issue. The shop can test for fuel and spark when it is not starting. Since it happens often it shouldn’t be to difficult to test. Once they identify what it is not getting they can concentrate on the individual components of each system.

2007 Ford RangerHi All, i had a cam belt failure, caused damage to values etc, so had head done at engineering shop.
Also refurbished injector pump, fitted 4 injectors(tested and verified ok), replaced copper washers at bottom of injectors and the injector seals.
On start up noticed small oil leak at base of back injector(closest to cab).
We removed the injectors and re-seated the seals, then refitted injectors.
On start up everything ok till we revved, then oil spewing out at base of all four injectors.
Need help please- what can be wrong?

regards
jcr


RESPONSE

It would seem the wrong seals or washers are being used. Try the old seals and washers as a test.

2011 Fprd EscapeRear wiper works intermittently. Sometimes it works half across the window, other times it wipes 2,3,or 12 times across .


RESPONSE

Rear Wiper Arm

First thing to look at would be the mounting of the rear window wiper arm also since it is easy to get to. There is a retaining nut on arm that at times may come loose and need to be tightened.  If the retaining nut is found secure the next step would be to replace the rear wiper motor assembly.

Ford F-150I have 2004 Ford F-150, 5.4 Triton V8. When I run it from cold start it runs fine for a bout 20-30 minutes. Once it warms up, it starts to sputter and stall out. Also, while driving when come to a stop, it stalls. We took the electronic throttle body apart, replaced the throttle position sensor, cleaned the body, and replaced the motor, all but buy a whole new throttle body. Cleaned the MAF as well. Had a cylinder 4 missfire and a camshaft sensor code come up so replaced both. I am at my witts end here and am about to pull out my hair because of this. Also replaced all of my spark plugs. Can someone please help.


RESPONSE

I might lean toward the ECT – Engine Coolant Temperature Sensor since it runs fine until it warms up. This can be caused by a stuck sensor reading. If the PCM continues to be told the engine is still cold once it has warmed the PCM doesn’t know and continues to flood the engine with incorrect amounts of fuel.

Engine Coolant Temperature (ECT) Sensor

An Engine Coolant Temperature (ECT) Sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and the resistance increases as the temperature decreases. The varying resistance changes the voltage drop across the sensor terminals and provides electrical signals to the Powertrain Control Module (PCM) corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor (pull-up resister) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.

The ECT measures the temperature of the engine coolant. The PCM uses the ECT input for fuel control and for cooling fan control. There are 3 types of ECT sensors; threaded, push-in, and twist-lock. The ECT sensor is located in an engine coolant passage.

Ford Code P0304 – Cylinder 4 Misfire Detected

Ford Code P0304 Possible causes

•Faulty spark plug 4
•Clogged or faulty fuel injector 4
•Faulty ignition coil 4
•Fuel injector 4 harness is open or shorted
•Fuel injector 4 circuit poor electrical connection
•Ignition coil 4 harness is open or shorted
•Ignition coil 4 circuit poor electrical connection
•Insufficient cylinder 4 compression
•Incorrect fuel pressure
•Intake air leak

The Ford Code P0304 means that the cylinder 4 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 4.

Ford F150When I turn off the truck and take the keys out of the ignition, my trucks electrical components such as fuel gauge and odometer is still on. The next day my truck’s battery is dead. Please help me find the cause. Thanks!


RESPONSE

Most likely reason would be the ignition switch(not the key and tumbler) is not being turned off. This can be from a failing ignition switch. If the key lock cylinder has been recently replaced there may be a misalignment issue.

1997 Ford F150My truck has been experiencing a rough idle. After getting a diagnosis I was told that my truck was running rich. I then had a full tune up done on my truck and change the fuel injectors. Now my truck is running lean. What’s wrong with my truck? Help.


RESPONSE

First place to start would be to pull any diagnostic trouble codes. Autozone will do this for free. Then post the codes below in the comments. For now I will just guess what code you have.

Ford Code P0171 – Fuel Injection System Too Lean Bank 1

Ford Code P0171 Possible causes

  • Intake air leaks
  • Faulty front heated oxygen sensor
  • Ignition misfiring
  • Faulty fuel injectors
  • Exhaust gas leaks
  • Incorrect fuel pressure
  • Lack of fuel
  • Faulty Mass Air Flow (MAF) sensor
  • Incorrect Positive Crankcase Ventilation (PCV) hose connection

If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. When there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced.

Ford Code P0171 Description

With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

Ford F150Not getting gas


RESPONSE

There are a few reasons why this might happen.

Not Getting Gas

  1. Out of fuel in tank
  2. Restricted fuel filter or fuel line
  3. Fuel pump not getting battery voltage or ground – Fuel pump relay – Inertia Switch
  4. Fuel pump failure – little or no fuel pressure
  5. No fuel injector pulse – Check ECM fuse first

1985 Ford Bronco IIGoes into every gear except drive. Anyone else ever had this issue or fixed it before on an A4LD 4wd Tranny? Ive been a professional mechanic for almost 10 years now and I’ve never seen a tranny that would go into every other gear except drive. I just really don’t want to throw a new transmission in it if its something simple or if the one I’ve got is still good and I just overlooked something.


RESPONSE

Tranny

The biggest indicator would be the color of the fluid. Wipe some on a paper towel and then dab a bit of fresh fluid on it to compare. If it is dark looking then the clutches are probably burnt and will need to come apart. If the fluid is clean, then there is probably an issue with the linkage.

MustangThe air conditioning system has extremely high suction pressure of 250 psi and discharge pressure of 170 psi what could be the problem.


RESPONSE

With R134a it’s common to see high side pressure between 2.2 and 2.5 times ambient temperature. On that same 80 degree day we would see between 176 and 200 PSI on the high side of an R134a system. The system operates in a specific range based on outside ambient temperature. High side pressure has a broad range relative to temperature because of heat load on the evaporator, humidity, airflow across the condenser, and engine speed.

High Suction Pressure

  • Loose expansion valve
  • Overcharged system
  • Expansion valve stuck open
  • Compressor reed valves
  • Leaking head gasket on compressor

Repair

  • Tighten valve
  • Replace reed valves
  • Remove some refrigerant
  • Replace expansion valve
  • Replace head gasket
