No codes, yet. Doesn't store between starts.
While driving in 3rd gear or 4th for a period of time the Cluster will show RPM's drop by 1k to 1.5k ability to maintain speed isn't altered. No other notice of issue until come to complete stop. At complete stop the RPMs settle at just below 500RPMs engine is shaky and the Check Engine light comes on. Accelerating from stop is now labored and struggles to get to speed.
Holding the RPMs high through a few gears and the RPMs return to normal and engine runs right for a few miles or less then process repeats itself.
If I notice the RPM's drop before coming to complete stop Holding high RPMs again corrects the issue for a short time.
Normally this only happens while driving. However more than once cranking cold and sitting while running it has occurred.
This occurs every drive longer than 10 minutes.
What are your thoughts? What can cause the RPM's to temporarily tank?
