Well, if we're still talking idle issues...My '92 has a real issue lately. Starts up just fine, then...after about 1-2 minutes into idle, she revs to 1200-1500rpm, then down to about 500rpms. I've removed, cleaned the TB, istalled a new gasket, tried to clean, then replaced the IAC...still no improvement. When I take it out on the road, I can feel the idle doing the same thing. Anybody else run into this problem...tired of throwing parts at it, without any real direction....Some help...anybody??????
