Hello all, was wondering if anyone in here had any experience working on one of
these? It has a 2.2L port injected engine. Having problems with fuel delivery I
think. Seems to lack power, and I can hear it backfire in the intake manifold
during acceleration. Also on start-up, after it is warm, the engine seems to
have a miss of the first couple minutes. I suspect a leaky injector here.
Unfortunately GM didn't make it east to check fuel pressure on this car, can't
find a Schrader valve anywhere. But I suspected the fuel pump was bad, and
replaced it. The car ran great for a couple months, except for the miss on
start up, but the problem is back now. Any help would be appreciated.
