I have a 90 D21 pickup 5 speed 2x4. My problem is that it will crank, run idle and I can rev the engine but when I put it into gear it lose power, won't go
When I put my truck in gear it loses power and shuts off. I have redone my timing chain, replace my exhaust, tune-up, mass air sensor, O2 sensor, fuel pump and filter, and distributor. I still have this problem. If anyone know of anything else please share your knowledge. Oh I also changed the computer.
