Tech notes If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. Apparently these wires rub on the bracket for the canister and it had worn through the protective tubing and broken the wires in serveral places. We have a large number of resources to help you repair the problem. Last Friday 3 October 2003 the check engine light came on again! Thanks for the post lgeiger13. The vehicle was taken to an independent mechanic who diagnosed that the engine blew a rod through the oil pan. I do not have alot of money and can't afford to let them keep fixing their problem.
. The local fire marshal and arson investigator investigated the fire and found no signs of malfunctions. I connected the test light to a ground and touched pcm wires 71 and 97 but I only turned 0n the key. No test procedures have been omitted. If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. This can be verified with a compression test if this is what is causing it.
Upon doing some research I found that the only way to replace it is to buy a new intake manifold so at this point my truck is stuck in the garage. Apparently these wires rub on the bracket for the canister and it had worn through the protective tubing and broken the wires in serveral places. Dealer has aligned the front end and adjusted the toe, camber and caster, however consumer still complains of steering wheel stiffness, dealer can not remedy. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. Engine recovered after a few yards and was driven home. We do our best to update these Ford check engine light codes as frequently as possible. Lol Ok I went out and replaced 1 injector and it did nothing.
I could really use an actual birds eye view of the engine vacume routing. The failure mileage was 82,000. This may cure the problem. Both Autozone and Midas read the code P1451 and said it was the Gas Cap. Several miles later , engine attempted to stall at 50 mph with all dashboard lights activated.
The approximate failure mileage was 132,000. The problem was a bad wire that came off the vent solenoid. Then to two small conectors behind the battery where harness begins, then down to side of transmission with two small tubes, but no canister as far as I can see ok I have a friend that used to work for ford and he thinks that I should ground the block to body two more times then ground the intake to the head to the block to the body then he wants me to change the injectors that dont work when the vacume lines r connected and see if the injectors were bad or the fuel rail he wants me to blow high pressure air through them to see if there is any blockage going on. Check engine light came on and preceded to flash, put truck into neutral and rolled to the side of the road where truck was shut off. . The car was a total in 10 minutes.
Please use the form on our Contact Page to get in touch with us. The contact did not disclose if a police report was filed or not and who extinguished the fire. At that point the computer retards the ignition timing just enough for the pinging to stop. But what the hell do I know. This information combined with proper testing procedures, specifications, and tools like a digital multimeter can help you fix the vehicle right the first time. The gauges were reading all normal, as well as oil and transmission fluid levels. Remember, these are manufacturer specific codes only.
Ok, over the weekend I was tring to work on this problem. Ok I really thought it was with the injectors but we are going to have to go further down the fuel circuitry than that. They will provide valuable info! If the coils are removable, and you are fairly handy with cars,switch two around, the problem will follow the bad coil. Here is how we suggest you proceed. If the problem persists the front oxygen O2 sensor may need to be replaced. In case the amount of the compensation value is extremely large The actual mixture ratio is too lean. This way car makers can get away with one coil for two cylinders.
These are listed in numerical order for easy searching. Spark plug was separated from the wire and lying on top of engine. If the problem disappears when the vehicle is in park and your long term is high that suggests a vacuum leak somewhere in the transmission actuator lines. If engine speed drops, go to next step. Please use the form on our Contact Page to get in touch with us. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. The vehicle was taken to a fourth dealer for diagnostic testing however, the technician advised that there were no failures.
I feel that replacing the engine is Ford's responsibility. If voltage is less than 10. If air intake system is okay, go to next step. This continued for several months until one day when I turned on the engine there was a loud bang and an obnoxious clattering. The fire was coming from the engine compartment.
