Re: 1985 Tempo 2.3L, terrible starting.
Well, we worked on the car some more today, here is the current situation.
If the vacuum is sealed up tight, we still get this issue.. requires WOT to started and half pedal pressure to keep it running for the first minute or two, then it will idle on it's own. If we don't keep it held down, it will quickly stubmle *like it is at 300 rpm* then just violently die.
However, the PCV valve we have from autozone is a universal one that has two plugs on it for the hoses, you are supposed to cap on one hole and the hole with the vacuum line. Odly enough, if we keep one of the caps off, creating a loud vacuum leak, the car WILL start rather easly. Most of the time it will even idle on its own, with a little roughness. If we plug the vacuum leak we created, the engine will just die. Wtf? I can tell the car is idling much higher with the unmetered air going in, and engine operation is fairly smooth actually. I tried a little carb cleaner in the Throttle body, and it just instantly died. Stupid backwards logic car. Carbcleaner should make you happy and rev!
So now that I have the car doing two things that seem to be against my logic of cars operation..
Any ideas? I'm fairly certain it is 'something' vacuum related, however, we replaced very vacuum line today. Thier is no way to adjust the idle speed with a screw either like normal Fuel injection.. but this is TBI, not normal FI.
