Well, I went ot get the emissions done today and it failed.
HC to high. traced it out to a cold starting injector that was mechanically
stuck ON. This would explain the idle being fine when cole and getting rougher,
the warmer it gets. WOuld also explain the horrible gas mileage I was getting.
BTW, the way I tracked this down was I disconnected the secondary fuel pump and
it didn't change the idle much, as too where it used to stall out.
well, now it stalls again if idling and disconnected.
BTW, how can I test the injectors?????
