Sja3893 Posted August 20, 2017 Report Share Posted August 20, 2017 When I try and maintain 30mph the car chugs and cuts out then on restart it starts hard. Seems to run ok on freeway any ideas Quote Link to comment Share on other sites More sharing options...
OldCadTech Posted August 21, 2017 Report Share Posted August 21, 2017 There are several things that can cause this, it should have set a code though. Assuming this is your 95 deville, please hold the "OFF" and "WARMER" buttons simultaneously, hold until all the segments on the display panel light up, copy the codes and post them here. How many miles on the vehicle? Any recent work done to the engine or other components? Quote THERE IS ALWAYS ENOUGH TIME TO DO THE JOB RIGHT - THERE IS NEVER ENOUGH TIME TO DO THE JOB AGAIN !!!
