Tips for you.

1. Try posting in the right section.
2. MKIII Supra Reference/Tech-Tips is not the right section.
3. 1988 turbo supra is not a useful thread title.

sounds like a MAF mine did the same thing. look on eaby for one. but before toy do that check for codes. is the CEL on?

Sounds like its running pig rich. possible causes: O2 sensor, leaky injectors, too much fuel pressure (restricted return, bad FPR), AFM issues...

as suggested start with a code check.
