Default 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.
