Hi,
I've got an EP82 Toyota starlet. Like most imported cars, these things run rich straight out of factory. I recently wack a SS mainfold, SR20 turbo in it. Car runs beautiful on boost but off boost is an issue......
It runs way too rich off boost (from 2000rpm to 3500rpm) to a point where it created mis-fire sometime. I've checked everything, thermal switch works, watertemp sensor works, O2 sensor works, engine light don't come up, change sparkies, change igintion leads.......ect still won't fix the problem.
Long shot here on this forums but someone might have an answer,
Thanks
