I notice when i'm in 1st and 2nd gear, while in stop and go traffic, my GT jumps a bit every 10 or so seconds just a bit, enough to make me loose good throtle control. It only does it when the engine is barely above idle, around 1000-1700rpm.

I've also noticed that if I leave the car on for 5-10 minutes just idling, the rpm will occationally drop from a healthy 1000rpm to 700rpm for a second once every 20-30 seconds.

Any ideas on whats going on here? I think it has something to do with my sparkplug wires as when I got the car, one of the plug wires wasn't all the way connected and occationally comes slightly out of the socket, but not enough to not fire. Even after I make sure the plug is on fully, it still does the same things.

You think that maybe it's the A/C compressor kicking in, that will cause the idle to increase.

I never run the A/C, so it can't be that. I'm going to spend some time tuesday hopefully and give the car a thorough look over.
