How hot should the ECM get after idle at 10 mins. History: Car running fine, turned it off in drive way and would not start (cranked by nothing). No MAL codes on scan master TPS was a little high but that was adjusted with no change. Changed the ignition module/coil pack. CAr turned over but idling rough and stalling in gear. Wire confirmed correct on the module to coil pack. Crank sensor installed this morning with no change. Hooked car up to Modis Snap on diagnostic tool and no codes. Set the car in back up mode and it smoothed out the idle when out of that mode rough idle again. Diagnostic tool stated ECM possible cause. Took ECM out and it was very hot for only running 10 mins. How hot should these things be? Never had it out before. Could it fry the TT 93 octane chip? Thanks
