I have a 2010 JK. It has really low miles on it.
5sp manual pretty stock, except it has new springs and shocks of of a Rubicon and stock wheels and tires off of a rubi. The tires are BF G muds.
The issue if it is
When I push the Jeep a little I mean hold the gear to 5K rpms the rpms stay there when I take my foot off of the gas and push the clutch. They stay there for a good 2 seconds. It actually stays up there longer the higher in the rpm range I am in. It is seriously driving me crazy. I have gone to the dealer and drove other 2010, and they all seem to do the same thing. It is probably not an issue, but it is aggravating to the point where I really don't like to drive the Jeep anymore.
My question is. Can I buy a scanner, and change it so the RPM's drop quicker when releasing the gas pedal? Of if not is this something that the dealer can change? What if I got a new ECU out of an 09?
