Gmc 1500 5.3L v8 idling issue

Asked by GuruHVH4K Jul 12, 2019 at 09:18 AM about the 2005 GMC Sierra 1500 SLE Crew Cab SB

Question type: Maintenance & Repair

Every morning we have this issue where the truck
starts up great, but then after 30 seconds or so it
will slowly stall out. It will stall maybe 4 or 5 times
before it will run correctly and then it's fine for the
day. Then tomorrow it all starts over. Jt is not a
relay issue and we replaced one of the master
sensors (i forget the name). It seems like a fuel
issue, but we are not sure.

The fuel pump and relay are fine. Nothing shows up on the code reader which is the odd thing. We also have a brand new map sensor in, so i don't think that would be a problem, but thanks for your reply. I will look into like the pcv valve and those things.
