Injector Help
Just installed new injecto0rs and coild today. Everything went like butter - no leaks, no issues going together. The car now has a miss from startup. Idles rough, it says I have full power, but I don't, can hear the flywheel hitting - not hard, but sounds like a click more than a bang. All vacuum hoses are in place. Took it out to see if it would work through it - no chance. Didn't get any better. Didn't seem to get any worse, either. No codes are set, BTW.
 Okay fuel injector replacement gurus, grasshopper needs to sit at your knee. Jim |

Re: Injector Help
I would say that one or more of the injectors aren't seated correctly.

Re: Injector Help
The coild are GM "545"s From JeffVette. The car ran great when it was cold, but had a hard miss after heat soaking. I thought it would be a coil breaking down with temoerature or an injector failing, so I replaced them both. Did not do a pressure test. I've had no issues with that previously and ran the car two days ago - cold, ran great; after heat soaking, like poop. New fuel pumps and filter, anyways.
Can you explain exactly what you mean by an injector not being seated correctly. I checked them over both in the fuel rail and after the install. They looked sqaure in the holes. Jim |

Re: Injector Help
Yep...x2! The FICs were a snap......it took me about two minutes to modify my four injector rail mounts and they worked fine from the word go.
