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.

Have you cleaned the MAF?

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.

alright ill try doing this. anyone have a writeup? i'm not really sure where the IAC valve or MAF are? lol

clean maf w/ crc maf cleaner spray and throttle body with throttle body cleaner. they really should be cleaned every time you put in an air filter.

IAC is idle air control and is top most arrow in figure 5

MAF is mass air flow sensor and is the arrow that is 2nd from top in figure 5
