1985 duke dieing issue, on and on it goes ! (Page 4/4) edfiero JUL 30, 01:34 PM I'm going to put some money on the ECM. Now that these things are 30+ years old, they will get flakey. And even a so-called rebuilt one can go at any minute. I've replaced the ECM 4 times in 2 years (for different problems) on my 84 Grand National. Lou6t4gto JUL 30, 05:51 PM that was my thought, I did Not have the "lock up problem before I put this ecm in. Akheron JUL 31, 07:26 AM I'm just gonna throw this out there, but have you replaced the EGR valve? I ask because your stalling problem sounds like what my car was doing. When my EGR failed, it would stall at low RPM's (at a light) and I would have to put it in neutral and rev it to keep it running, but would run smooth as silk at highway speeds. Granted, my EGR valve failed catastrophically and it was obvious that it needed to be replaced, but I'm wondering if yours is on the frits and is about to fail completely. Lou6t4gto JUL 31, 01:09 PM EGR was Replaced, and the EGR has nothing to do with the Converter locking up Lou6t4gto AUG 14, 07:41 PM replaced the ECM with the original, still stalls, didn't even get 50 feet , engine was not even warm yet !
