Help, my 91 audi 80 keeps dying
 

Have had this car for a couple of months and has always had infrequent idle speeds sitting and driving ranging from 1500 rpms to 2500rpms. A couple of weeks ago it started back firing and would die while driving or sitting, sometimes taking a couple of days to stay back up. The fuel pump works (unplugged the relay and fuse for the pump to check it out). And I don't seem to hear a vacuum leak either. Could someone please help.

Hi, what did you do since then? Runs good now? or did you check the coolant temperature sensor and wiring connecter ? etc. x19
