I have a 94 PGT 5-speed and it misses at idle sometimes when it gets hot. It doesnt effect the performance, its just annoying as hell. I've changed everything plugs, wires, fuel filter and nothing works. I did compression and even a tune up yet nothing. Dont know what to do next???

partially cloged fuel injector?? what octane gas do you run? you should use 91 or higher. Maybe try running a complete fuel system cleaner through it.

yeah I also put a fuel treatment bottle in and it still happens. I have and will always use 93 octane for my baby.

Well, did you check the TPS? I'm picking up my third one tonight. They seem to go out and start acting funny about every 50,000 miles. I had a bad idle problem for the last month, so I switched back to the old TPS last weekend. Now the idle is fine, but it bucks under accel / decel, just like it used to when I replaced that one way back when. They're spendy, but easy to install and adjust. And they have a big effect on this - it's what tells the computer how open the throttle body is...

Problem is FIXED:D :D :D New set of plugs that are guaranteed for a lifetime. Missing is gone although i think it idles at bit rough.
