ok, got the new plugs in and it idled much better, but still has issues due to the tps being ****ed up. i put a can of seafoam in the fuel cell just to "clean everything out" and noticed nothing. well on the way home yesterday at a light, light grey smoke came out the exhaust...nothing bad, just light smoke. i reved it a little to make sure it was still running (the tps makes it die sometimes and i dont realize till it's time to drive, lol) and it didnt really get any worse, just kept on lightly smoking. i finished my drive home about 15 miles away and nothing happened the whole way, then when i got to my street i was turning and going REALLY slow (re-sdoing the street and its bumpy) it did it again. this time however it was BAD! it was a huge cloud and it even came in the car a little bit. it smelled but i dont remimber what it smelled like, all i remimber is it wasnt sweet like coolant. the cloud lingered there for quite awhile as its about 1/2 a mile to the end of my street where i live and by the time i got there you could still see it pretty well. the thing that bothers me is it runs like nothing is going on at all! no sputter, no nothing! what do you recommend i do? i just got the motor in and wired up and cannot really afford anything more, but i dont want to tear it up either

Sounds like you put wayyyy to much seafoam in you gasoline. Just my 2 cents though.

1/3 can goes into crankcase1/3 can goes into gas tank1/3 can goes into the intake manifold.

had NOTHING to do with seafoam, brake booster was leaking and filling with fluid, it would get into the intake and BAM, grey smoke. replacing MC and brake booster on monday
