S50B30 M3 e36 idle problem

The problem was the ECU, in the video I am triying to plug and unplug the MAF for see the reaction of the engine.

Hi, how did you solve this problem, i have got the same, did you just change Ecu and engine goes fine?

Yes, the problem was the ECU, this car gets on fire for the catalytic converter. I think the fire broke the ECU. With the new ECU the problem was solved.
