folerx's video: Kajza M3 E36 3 0 hard shaking and rough idle avi

After changing instrument cluster and 8 min driving engine start to hard shaking and have low idle. We try to reset ecu and this help for several minutes, engine run like new, but after half hour shaking start again. On comp diagnostics no any error codes, vanos work ok, camshaft have ok angles...Car is fast, strong, with excellent throttle response......When MAF is disconnected engine react...My board computer is died in this days and this is shown in diagnostics. I will make big service on engine which include valve adjustment, measure fuel pressure, oil pressure, compression test, throttle body basic setting / exhaust synchronization, oil change, clean idle control valve etc etc... FIXED: new cluster wont pass speed signal from diff to ecu, so ecu cant make good fuel tables. this is cleary visible on onboard comp which dont show up any info about consumption.
