Hey all, have a 1990 MKIII Supra, but is been giving me trouble lately. Other than this it has been completly reliable, got it water pump timing belted it, upgraded the stock slipping [ took 4.5 grand to get moving ] clutch with an ACT HDSS clutch. Well on the problem, sometimes and I say only sometimes because it will idle fine at some points but not others, its definately running rich, sputtering, has a high idle [ 2 - 3 grand ] , once your letting the clutch out with the high idle it goes down and if it dies it takes quite a while for it to start back up again. You can smell all the fuel when its cranking too. When its sputtering, you can gas it up to get it going and a puff of black smoke comes from the exhaust.
Any help is appreciated. I"ve already checked the AFM sweeping resistance as the door opens, continuity between te IAT sensor. I'm just stumped, the high idle would be explained by a vcuum leak but then why would it be only some of the time ?
