my tbi is acting good, day to day and acting like crap most of the time, it is an 87' 350 TBI in the morning it wont choke itself (fast idle) i punched the gas once to the floor before i started it after school today, and it sorta worked, what is going on here, someone help please, bye bye.
Yes I too have a fussy TBI in my 90. It runs nice and powerful sometimes and other times the check engine light comes on intermittently. I think the Throttle Position Sensor on the ones we have, with the choke, is delayed or bad design or something or they could just be shot. Sometimes mine delays so much. I have a newer TBI from I think a '91 or a '92 It has a different TPS all together and no fast idle tabs like on the earlier ones. Was going to put it in but I think I'll wait until I put the other engine in. Try to track a newer one down from an autowrecker, make sure you get the plug and wire too.
Hope that helps
