I have a 96' 2.5 leg. GT. Started it up cold and it sputtered like it was starving for gas or weak spark for about 5 seconds then rev<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/ohwell.gif ALT=":\"> ed @ 2,000 rpms for another 5. Then it kicked down to a normal idle speed. Plugs, wires, fuel filter, air filter all look good. Would like to hear your ideas.

Could be a separated vacuum line.
If it does not happen again, I wouldn't worry about it.
ECU probably compensated for the low idle and kicked it up to 2000 rpm for a few secs.

It is now 3 days later and same symptoms are reoccurring. I cant find any vacuum leeks or seperated hoses. Once again, the car runs superb after about 15 to 30 seconds. I would appreciate a bit more of your superior knowledge.

It might be that the Idle Air Control valve might be going bad. Try this, when starting up the car and it is sputtering, trying to run smoothly, press the accellerator slightly. Does the car rev up and run smoothly? Let go of the accellerator. Does the car start sputtering again? If so, then it is definitely the IAC. It might not be working right when the engine is cold, but once it warms up, it starts to work right. I think that might be the problem.

Kevin, now you have me thinking. The engine light isn't on but I know there is a leaking cam or crank seal. Haven't pulled the timing cover off yet to see. Maybe oil leak is fouling a sensor? <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/grin.gif ALT=" >D">
