I just put a new rebuilt head on this 1996 1.0 and it runs well enough except the old problem (besides a blown head gasket) is still there. It randomly floods and wets the plugs and is hard starting. It also does not idle well. The idle comes up after abut 15 seconds and will keep running if it is warmed up. I am trying another map sensor and replacing the tbi fuel regulator diaphragm. I have a spare TBI sitting on another engine to steal parts off of. Thanks!

Have you checked the fuel pressure at the throttle body? Before starting the engine have you checked to see if there is fuel in the bottom of the intake, too see if the injector might be leaking fuel while the engine is off. |

That's good news. If you are interested in getting rid of the one you took out let me know. I am working on a way to clean injectors and need a known bad one to try and clean. |

I have an injector with an intermittent no start condition..... Not quite what is discussed here. I've used it a couple times as a test replace to see the short term fuel trim differences and to diagnose the O2 sensor cel. turned out I had a bad injector that did not leak but would constantly overfuel the engine and O2 was tripping the cel because it never got lean enough to change voltage. Test injector seemed to solve the cel. New injector was instant fix. I have at least 1 injector I could part with for clean and test.... Is there a voltage and/or resistance test that you can put them through after cleaning?? |

Let me start a thread just for that. I don't want to sidetrack this one. |
