Ready to race!
Hello All,
This forum and the other golf ones have been invaluable to me for my VW service needs over the last 13 years. Joined the Acadia forum for my new kid hauler and the people all just point to the dealer and fear self diagnosis like the plague and are down right rude about it.
The car:
2017 GMC Acadia 3.6L Denali 21k miles
Issue: car is perfect except it stumbles at idle in park/drive/neutral ever so slightly. Like someone is nudging the car. Runs totally fine other than idle. No codes or errors. Dealer won’t help as they can’t feel it (like all dealers). Unsure if related but it smells super rich when warming up in the garage in the mornings (door open obviously).
Tries so far:
Vacuum lines seem fine
New air filter
Snugged throttle body bolts
Cleaned throttle plate
Reset throttle body
Fresh gas
Injector cleaner run through gas tank
Further thoughts:
Spark plugs to be changed
PCV?
Idle air control valve?
Clean MAF maybe?
I’m at a loss if none of that works. Any thoughts from the VW self maintenance masters?
Hoping spark plugs and maybe some spray cleaner on the MAF and IAC valve will smooth it out.
