Background:
1.8L FI w/ Stock distributor I Recently removed engine to sort various problems and reinstalled. I can get the car to start and idle per spec and Dwell is w/in spec (45). BUT..... When I jump in the car and blip the accelerator pedal (not significant RPMs about 3500-4000) the car dies. However, when I hit the throttle cable from the engine bay it's fine... no stalls. What would cause this? - Badly positioned or tangled accelerator cable? - Funky distributor cam messing with dwell? - Vacuum issue? - Air Flow Meter? When I go to restart, it won't fire and I have to reset timing and start the process all over. Any troubleshooting steps or tips appreciated! Greg |

QUOTE(moldygreg @ Aug 8 2016, 10:43 PM)  ....I have to reset timing and start the process all over. What do you mean by this, exactly? If the engine runs normally when operated manually, then I would focus on the throttle cable, but the only reason I could see that causing the car to die would be if it were creating/interrupting some kind of ground-path that's screwing with the ECU. Did you reinstall the ground strap on transmission? Check all your grounds and try connecting a jumper cable between the engine block and the negative terminal on the battery, then check it again. |
