Why Does My Car Have Rough Idle?!?!?!
My car has run fine until this point. Last night I raced 2 Supras on the highway to about 140. The car ran beautiful... strong as ever. I then get off of the highway and all of a sudden the car has a hard lope to it at idle... kind of like a cammed out V8 car or something. So I take it home and let it sit overnight. Fire it up this morning and still the same problem. I also noticed after I got off of the highway a slight exhaust leak that was not there before... maybe a gasket between the turbos and DP or between the DP and MP. Could this contribute to the problem in any way? The only other problem that I had today was in third gear when I wrapped it out to 8000rpm and the 2nd turbo NEVER kicked in. WTF?!?! Any ideas? Anything at all would be appreciated. Thanks.

Ohhh By The Way... my car is a 93 R1 w/ full exhaust and pushing about 16psi of boost. The idle is REALLY bad in the morning and on start ups and smooths out just a bit after I drive for a little ways but not much. Still feels very powerful though. Could a fouled plug or something cause this?? Thanks.

It's not the MAP sensor/hose...cause the car won't run strong, proabably 5 or 6 PSI of boost if the hose popped out.

if the 93 model has a map sensor,check that the hose didnt come off from it,its known to pop off.Check other vacum hoses as well.
