italian89supra · 07-04-2011, 06:50 AM

on my 89 supra turbo 7mgte (cutout exhaust, hks ssqv?

ill warm it up and the idle will jump constantly if i dont give it a little gas

will be fine for a range of 5 minutes and then run extremely lean like high 17s and ---- on wideband

then idle starts to go up and down and eventually dies

im thinking gasket possibly, idk new to turbocharged cars

just recently put in a megan racing aluminum radiator and fixed a short in fan near battery but i dont think that would matter since it doesnt overheat

any help would be greatly appreciated, kinda sucks putting new parts and fixing then something else happens thank you for all your input
