idle/running problems
hey
So I have an 88 Camaro that i put a 350 tbi in and it has this strange idle problem. the rpms fluctuate up and down as much as two thousand rpm and at times the engine just idles down so much it dies. I am totally clueless. Any ideas?

Welcome aboard thirdgen.org.
Did you install a 350 TBI ECM & all, or put a 350 under your LO3 TBI system?

Re: idle/running problems
How did you fix it? Did you replace the TPS or just readjust it? Not sure if it even is an adjustable TPS.
