Re: 90 350 TBI wont idle down.
I dont remember the code, I think I have it written down I will look for it. The first engine was a 350, I did not change the ECM. I used the junkyard engine's intake manifold, and it looked like it had never been off. I have checked for vac leaks and found none.
After swapping engines I did install an open element air cleaner, however the truck ran the same with or without an enclosed aircleaner.
The truck is a factory 350 V-8, with a 5 speed manual transmission. I havent messed with the IAC.
