WOT it feels good to so i dont know, mabe fuel pump?throtle positioning sensor?plugs and wires???? i dont know. please help
Man, that can be a few different things. Get a scan, OBDII and see if it shows anything like 02 sensors that arent working poperly. But not the scanners at auto parts stores, the real one that the dealerships use.
Some pCM's will not show an SES light when there's a problem.

Definitely need some more info on diagnostics. Need to know whats going on with the O2's and some other sensors and if you are throwing any codes or anything. If you just start doing stuff you are just going to be throwing money at it hoping it goes away without actually knowing whats wrong. At the very least get the codes scanned and see what pops up.
