Well I finally found a good donor for my TBI 5.7 from my 1994 truck. I'm thinking about using the Edlebrock Preformoer intake and carb but I would love to keep the throttle body set up. I have 2 problems though. 1st is I'm having trouble finding a good STANDALONE controller and harness for the TBI. The second problem im having is that although the stock engine in the 1994 is a GREAT running and torque-y little motor, it has a rough running issue at low rpms that it has had for years and I cant seem to pinpoint the problem. I want to fix it before I put it in the 1981 so i know its gonna run great. It runs great at idle, acceleration, and cruising, but low RPM coasting and parking lot speeds it runs rough and almost sounds like its loping. Smooths out as soon as you give it throttle. I know a Carb would eliminate the issue but the thought of passing up the convenience and performance of the TBI is hard to pass up. Any suggestions?
