If #6 clears and the one you swapped with shows up, you know it is the cable. Start the engine and read the codes again. Take the wire off #6 and swap with another one. Why is number 1 highlighted? You can verify if it is in fact the cylinder, the cable or the coil.
#Ford engine codes 306 drivers
It now runs beautifully.Ĭyl #6 is drivers side closest to the windshield. Added sea foam to the tank prior to filling it. I changed all plugs and wires as well as the coil. I just had the same issue but with cyl #4. Any help or advice is greatly appreciated. I'm trying to fix this on the cheap, as I'm super broke. Where are the injectors located, how do I remove it, and it is possible to clean/soak it instead of replacing it? Also got a bottle of Sea Foam treatment, and will use it soon in hopes of it cleaning the injectors. Heard it could also be cylinder pressure? I put in a little bottle of Lucas injector cleaner last night. I now mainly suspect a problem with the fuel injector (maybe fuel pump/fuel system?). Went to two separate auto parts stores to check the code. It will start flashing a yellow check engine light while I'm at a stop. Second was today after the new plug, and another hour drive.
First was after replacing the ignition coil and wires, and going for an hour drive. a little 5.25 fl oz bottle of Lucas Injector Cleaner w/75% full tank Sounds kind of like a low "jub, jub, jub." at sitting idle.Ĭhanged oil and filter, then after the inspection I tried things in this order: Engine stumbles a bit at idle, which I believe it has been doing for some time. It threw up the OBD code P0306, which apparently means cylinder #6 misfire. My check engine light has been intermittently on for some time now. I don't know where everything is located on my engine, such as fuel injectors, random sensors, etc.
Please go easy and explain what you mean. First off, I'm not very knowledgeable of engines, but am capable of figuring things out and doing basic maintenance.
