When I first start my truck it barely wants to idle but if I give it gas it stays running until of course when I let of the gas while taking a corner or just sitting in traffic and it dies. After the engine gets warm the problem is far less however I still feel the engine is idling lower than it should (about 500 rpm). No check engine light or codes stored. Any help would be greatly appreciated. I’m taking the truck in next week for a Service Ride Control Light (truck sits and rides fine btw) but figured I’d have it checked before I end up with a costly repair. Truck has 130,000 kms on it.
Thanks,
DBC

GM scanned and tested. Can't duplicate my complaint. What are these trucks suppose to idle at in park and drive?
Thanks,
