[Suzanna]

Hi,
My brother mentioned about the Forum and sent me the link to join. I’m new to owning a Jeep haha like 2 months now, I have had a few minor problems here and there so far with my 2015 Wrangler though I love her. Recently the track gauge lol RPM is sticking. (New to this) Im sitting in my garage after arriving home from work yesterday..
Jeep not idling higher when driving... Hoping to get some great advice on things going wrong and meet some fellow Jeep owners ! Thank you

Is it throwing a check engine light? If so, have you scanned it for codes?

 

[mrjp]

Welcome Lookin great. Like @Chris said scan it for codes if you don't have a scanner autozone will scan for you

Welcome.

Is it stuck, or does it move when revving the engine. With the key off, does it go to 0?

Do the instrument self-test... Might reset it (and it's fun to watch)


1. Begin the test with the ignition switch in the OFF position.
2. Depress the odometer/trip odometer switch button.
3. While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the ON position, but do not start the engine.
4. Release the odometer/trip odometer switch button.
5. The instrument cluster will simultaneously begin to illuminate all of the operational segments in the VFD units, and perform a bulb check of each operational LED indicator. The VFD segments and LED indicators remain illuminated as each gauge needle is swept to several calibration points and back. If a VFD segment or an LED indicator fails to illuminate, or if a gauge needle fails to sweep through the calibration points and back during this test, the instrument cluster must be replaced.
6. The actuator test is now completed. The instrument cluster will automatically exit the self-diagnostic mode and return to normal operation at the completion of the test. The actuator test will be aborted if the ignition switch is turned to the OFF position, or if an electronic vehicle speed message indicating that the vehicle is moving is received over the CAN data bus during the test.
7. Go back to STEP 1 to repeat the test

My RPM's will hang sometimes when i'm downshifting coming to a stop, I never could figure out why and I don't have any Codes.

A dirty Throttle Body might cause that, the EGR valve dumps alot of tarry stuff into the intake manifold. Not sure if the 3.6 engines EGR's the same as a 3.8 or not.

Honestly, I'd have to check, but I think Jeep did away with the EGR valve with the 3.6 design. Changing the one on my 08 3.8 sure was a pain.
