question on rough idle

I have a question. My idle was getting a little rough at stop signs and lights. I thought it was because of the timing belt getting stretched. I have 99,000 miles and it was over due. I got it changed nad the problem still exists. I tried replacing the TPS and had no luck. what about the air filter? could this be it? I know it needs to be cleaned. i cant get the box open. one of the screws is stripped and i'll have 2 break it to get it open. I am beginning to think that hwen the dealer did the timing belt they got the cam timing off a bit. let me know what you guys think.

Have you done a basic tune up? Spark plugs , fuel filter done lately?

Start with these if not done.

Hey, dbenney. I had a similar problem with my ZTS after it jumped timing and flat out died on me. Still under warranty and the dealer got it running, but my idle was rough from then on. In fact, sometimes when I would come to a stop it would drop below 750 RPM and bog like it was about to die. Dealer took it in again and pronounced that all was "normal". Of course. Then about a week ago I received and installed an Idle Air Restrictor from Fast Forward. Shifts are smoother now, although mostly when I'm driving easy, but a reallly nice side-effect is that my idle is now smooth as glass and never drops below 750 revs. If all else fails you might give one of these a try. See if you can find a used one, though, because they just doubled the price on the damn things. I'd say it's worth the $39 I paid, but probably not $77. Good luck.
