Rev Hang Issues After "Recall" - Manual

[autotragic]

by law they have to do the recall if its in the shop for any other repair

Whose law that's certainly not a federal law. I had my rear end rebuilt under warranty and they didn't do any recall work for my clutch.

The problem is, I don't want the clutch, it's terrible. I'd rather go aftermarket.

Not that it's going to help you but in case somebody else sees this with a manual transmission and doesn't want that crappy software installed in their Jeep go on eBay or Amazon and get you an OBD2 lock kit so the dealer just can't plug in and update software without your permission.

Have you tried the throttle position relearn? Helped twice so far after the dealer reflashed the Jeep.

Get in vehicle, put on seat belt, press button twice to put it into Run (no ignition / engine off). Wait for the engine light then slowly go the full range on the accelerator pedal, five seconds down, five seconds up, repeat. (Arguably one is enough). Thirty seconds seems to be too long, two seconds means it'll likely miss some of the blank spots in the sensor output (so you could get dead zones). Foot off accelerator, neutral, clutch in, hold for ignition..

I did this, and it seemed to work for about a week, but do I need to be in 1st gear while pressing the gas for this to work properly?

That's good to know. I think eventually I'll get a tune as I think I have the ECU that has been cracked ('21).

The only thing i touch is the gas pedal. Up and down slowly a few times in around 20 seconds.
