A 1974 Duster - My 2nd one, 41 years later!
Making a change. The Fitech TBI, keeps dying. Sick of this. It starts, it runs and then for no reason it shuts off as if the key was turned off. IAC's are right, runs great when it's running. Some sort of RPM noise interference. Lots and lots of people are having the same problems. This guy on Fabo also describes the same issue:
Fitech EFI Rpm Noise Solved
Anyways ditching the Fitech TBI unit. Going to Edelbrock's Pro-Flo 4 EFI System seen here:
Edelbrock Pro-Flo 4 EFI Systems 35900
It has shipped and will be here tomorrow. I have already removed the Fitech unit, I will start the Pro-Flo install as soon as it gets here.
