I have a question for you guys. The first time I ran my truck I ran it with just an intake. I ran a 16.4 at 83 mph. Now I ran it recently and I ran a 16.3 at a 83 mph with cold air intake, header, Exhuast, Electric fan and more traction. But my check engine light is on. will the light make a difference or is that normal. When I didnt have a check engine light I beat integras gsr's, civic si's and celica gts's. Which are all 15 sec cars. Is it my driving or the check engine light.

Peace Tacomaracer

Try disconnecting your battery for 5-10 minutes for the light. If you are beating gsr's and you run 16.3, they can't drive at all or you are at VERY high altitude. I ran 14.86 in my 94 gsr with i/h/e and 15.5 when it was stock. My truck now ran a best of 15.2 and I'm at sea level.

I tried that but I have a bad idle fuel valve sensor or something like that and it comes right within a minute.
