So I recently installed a long block 350 in my truck. I upgraded to an Elgin 920 cam. Currently still have the stock tbi. It shows code 33 for high voltage at map. New MAP, IAC, EGR, and distributor. I have fogged the intake, tbi, and all vacuum lines with carb and choke cleaner with no change in idle.
Truck idles rough which I know is due to the stock tbi. It’s runs decent when throttling while in neutral or park, but when putting it under a load between 1500-2000 it pops back through tbi and shuts off. Any help as for which direction to look would be appreciated.
