Intermittent loping idle while at stop light or parked and idling 2.3L
I’ve got a 2011 Ranger with the 2.3L & (auto) I have just shy of 6K miles since I got the truck. On one hand I can count a few instances where I’ve had a loping idle that sort of drones (Think the sort of drone from un-equalized windows down in a sedan buffeting) in the cab. The scenario typically occures while sitting in a drive through or stop light. Not sure if it’s related or not but a few times I have had an intermittent bouncing idle while coasting or holding 45-50 mph. Truck still going but tach and engine idle slightly bouncing. Turning the truck completely off or just waiting 4-5 minutes seems to cure the issue.
Before I take the truck in to have it checked (worried it may not do it for dealer resulting in wasted trip + time & gas), thought I would see if anyone else on here has experienced the same condition with their 2.3L automatic, or if it could be some sort of inertia associated with an accessory drive such as the A/C compressor, or the clutch fan etc…. I have tested and examined the intermittent rough idle with and without the A/C on so that’s why I suggested possibly the clutch fan engaging as it has been really hot in my area over the last few days.
