rrs814 Posted October 15, 2002 Share Posted October 15, 2002 OK, it's not my Reatta, but I don't know where to turn! My '90 Eldo was missing like crazy! Sputter, jumping, "lurching" etc. Took to AC/Delco mech and did tune up with new plug cables-fuel filter-2 ox sensors-temp sens-ECR valve. No good. Tried Techron inj cleaner...still bad. ALSO will run OK SOMETIMES UNTIL AC or Heater turned on then it misses again! ANY input greatly appreciated. Link to comment Share on other sites More sharing options...
Guest Buick Mike Posted October 15, 2002 Share Posted October 15, 2002 It might be a bad ground connection. Find out where they are and check them. Mike Link to comment Share on other sites More sharing options...
