engine stalls / floods @ idle , also surges

Asked by dlorent Jul 16, 2016 at 03:47 PM about the GMC C/K 3500 Series

Question type: Maintenance & Repair

I have a 1990 Bounder motorhome with 3500 series GM running gear 454 w/ automatic, engines stumbles and surges at low speed. It has throttle body fuel injection, it will flood out and die often at idle , with air cleaner off you can see injectors dumping a lot of gas when it is acting bad. Does this unit have a computer?

1 Answer


when idle spray some carb cleaner around the intake and parts...does the idle change...LOOK FOR A VACUUM LEAK?
