94 z28 Rpms bouncing at idle
I have a 94 z28 a4, just hit 131,xxx miles. Have pacesetter mid lengths on it and recently had a shop replace the exhaust gasket on passenger side. Then the next day car was running horrible. Looked under hood and found out that the shop didn't run a plug wire correctly. It was touching header and burnt through it. So I replaced the wire and it was running better but then car started revving by itself while I'm at a stop will bounce from 600 to about 1500 at the most. I've had this problem b4 I swapped the AIC, new egr valve, new smog pump, and swapped opti and wires and plugs with in last half year. Ive got rid of this problem for a couple months and it seems to be haunting me lol. Any ideas what could be causing my problem any help will be appreciated. Also should I change spark plug that the burnt wire was running to? Thanks and have a good day....

O ok I'll have to recheck the egr. I still have it all cause I live in California. I want to delete it all abd run LT's lol but maybe after next smog. But I'll check vaccum lines for any leaks thanks....
