can't figure out this problem....help!
can't figure out this problem....help! ive changed out the fuel filter, oil, plugs, wires, both o2 sensors, and i still have this hesitation at idle. i've seafoamed it as well. the car will shake sometimes, and the idle drops a bit. once i get going it sputters then finally goes. every now and then ill haev a backfire. any ideas? all this maintenance has been done in the last few months.
Try cleaning the MAF, the MAF screen, and throttle body. Simple to do and well known for causing those types of problems. If that doesn't work try cleaning the IAC valve. I've yet to do that on mine but it's solved similar issues on other cars I've owned.
