Question about 1997 Toyota Supra
And the engine misses terribly for 3-5 minutes. Not it happens constantly
Is it only when you first start it up, and then it clears up? Is this in the rain? What weather affects it? My 300ZX TT had problems like that in the rain sometimes when I first started it up. What I figured was that I was getting too much moisture on the mass air sensor and it was causing it to tell the ECU to fuel the engine incorrectly. Being a hot-wire MAF sensor, once it heated up and burned off the condensation, the fueling was controlled properly and I did not have the problem anymore. I don't recall offhand if the Supra also uses a MAF sensor or a MAP sensor to determine airflow though. Post up some more info, especially some details on when you notice the problem (weather-wise, as well as if the engine is cold or hot, etc) and we can try to go from there.
