Years ago I had a 74' 2.0 FI that was running crazy rich, I tried what seemed like everything. I took it to a local shop giving up and figured just spend the money. Really glad I did.

Wound up the ECU was double firing 2 of the injectors. The shop bench tested the trigger points to be good, but the injectors themselves were blinking the little diod tester thingy way to fast on 1&3 or 2&4, can't remember the pair anymore.

I was actually there when he discovered this. One of his Mechanics ran home and drove his 75' 2.0 914 into work. We swapped ECU's for a dummy's test, ran perfect.

Back then, I just had my ECU rebuilt for I think $75.

Might be something similar? (IMG:style_emoticons/default/confused24.gif)
