Driving the 85 GN, car running perfectly, come to a stop light engine stutters just slightly and SES light flashes. Runs fine to the next light, again engine stumbles and SES flashes a couple times very quickly. Leave light go about one mile car stalls. Push to side of the road, turns over fine but no start. Tried to check by jumping OBD port and the SES light is on solid and does not flash at all. I could smell a hot plastic smell but had no idea where it was coming from. I towed the car home and tried to jump the OBD port again and light does not flash. I pulled the ECM out and it is so hot I cannot hold it with my bare hands (at this point the car has not been running for almost an hour but the key was in the on position as we towed it about 3 miles). I have a power logger attached but did not try hooking my laptop to it yet. (got dark too dark) Wondering why the ECM is so hot. I know it's not supposed to be hot but don't know what would cause it to get that way. Likely a bad ECM or is there something that would cause it to get overheated? Hate to stick another ECM in to have it get fried too. Mods are in my signature line. Any suggestions???? Thanks!
