Right i had this problem about 2 days ago an it seriously pissed me off. Basically it would run fine on the autochoke (about 12.5 afr) but instead of leaning out to 14.7 on tick over it went down, off the scale on my wideband which is below 10 afr and was kicking out black smoke an would not even run. I changed everything an was about to smash it up, but for some reason i decided to change the lamda sensor again as i fitted a crap universal one ( only one they had at the time ) and fitted a manky second hand one. Then the car ran fine.

I ran mine with that problem on the computer an you could see that the injector pulse went through the roof when it got upto temperature.

[Philsutton]
