Check Engine Light and Codes Again 200 1992

posted by  someone claiming to be CB on  Fri May 1 20:35 CST 2015 [RELATED]

"When i start the car up it doesn't want to idle and will stall. It only keeps running with the help of the throttle. Then after a few minutes it will idle on it's own, but kinda lumpy."


On an older CI system --- K-Jet...with its Lambda Sond, if the O2 sensor was new, and the rest of the FI system was fine, but the idle was rough, I would try adjusting the CO, which you can do manually. Turning the adjuster to smooth out the idle and then checking the CO level.

The same would go for the LH 2.2 system which has a CO adjuster pot on the AMM.

But with the LH 2.4 there is no manual CO adjustment - it's supposed to be Self Adjusting. When the O2 sensor heats up, it idles, but poorly.

I think your problem is in the Lambda Sond loop.

good luck at Arts
