Re: TBI throttle positioen sensor

I have a caddillac with the same problem at half throttle.I asked a friend of mine who is a mechanic and he says it's the TPS (throttle position sensor) so I would have to assume that you problem might be the same. Hope that was a little help. Good luck.

Re: TBI throttle positioen sensor

TPS sensors tend to die on chevys. so it would not be the first time.

if that does not solve the problem look into your fuel filter. not enough pressure in the fuel rail will cause a similar problem. same with a gooed up tank filter or failing fuel pump. failing fuel pumps also lead to similar issues.

and last, check the ign system. TBI coils fail, along with the guts of your distributor. slim chance of that stuff with what is going on with your motor, but if all else fails look there.
