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.
