Suddenly this started to happen after I changed my idle to openloop en played with my air density table:



I know the idle and air density settings shouldn't matter so could it be a defective wideband? It's a innovate mtx something with the LSU 4.9 sensor. Oh and btw, I ran a little too rich last week because of a major human error �� . That rich that there was a lot of unburned fuel in the exhaust and a huge cloud of black smoke. I calibrated the sensor yesterday so that couldn't be it..

What I would suggest you try, based on the picture.

Turn off EGO and see if oscillation goes away. If it does, then that is your cause. I believe that it is.

Thanks! I actually turned it off right after posting. The oscillation didnt occur anymore. But how can I fix the issue to use ego again? Turning it off is more of a temp fix.. what can you suggest? I sadly need to use the ego correction because I have to daily the car and the ve table is not great yet...
