I'm hoping someone can help- about at my wits end with this one. I've been having problems with my 2001 V6 Escape having cylinder misfires for about a year with no luck finding the cause. The car stumbles and pops on startup, usually on acceleration, and sometimes when cruising. I've had P0300 through P0306 codes - changes all the time and without any discernible reason (i.e. doesn't change when I move the ignition coils). Right now it says cylinder misfire on 1,3, and 5. It also smells like gas - I believe it is running too rich. I've replaced just about every part and sensor I can think of: ignition coils, plugs, IAC, MAF, PCV valve, EGR (sensor, valve, and solenoid), coolant temp sensor, air filter, fuel filter, fuel pump, fuel injectors, 02 sensors, camshaft sensor, crankshaft sensor, and probably more that I can't remember. I've done a vacuum test and gotten good results, and a compression test came back 170 across the board.
At this point, I'm pretty much reduced to guessing that one of the parts I put in was also bad - the MAF maybe? I'm out of ideas and hoping someone out there has a few (helpful ideas, not "shoot it and buy a Dodge" ideas.
) Thanks for any help!
