Good Morning Chaps, yes that whole thing sounds very odd, I must say I have never tried running on one injector, that is good to know for a trial.

The system should be on closed loop mode at start so I doubt whether a lot of the sensors should really have effect.
It certainly sounds like it is substantially overfuelling.

I must agree trying another computer would be my next thing, it sounds like the start program is really "whacked".

This is just a guess, but base injector timing is the computer.

I would be inclined to remove the computer take the cover off it and have a close look at the printed card for any obvious damage or component failure, quite often it saves a lot of mucking around.

Edit. That overall symptom and the idling is not that far from a "limp mode" kind of effect.

Cheers, qldit.
