I had to use a battery booster to start my 2007 Wrangler X yesterday and when it started, it revved up fairly high. It idles fine, but when I started to drive it, there is very limited acceleration. I drove around the neighborhood for about 15 minutes, but no improvement. When I step down on the accelerator, I get a couple of hundred RPM but no more...

Sorry if this has already been addressed on the forum, but could not locate anything.

I have an appt with the Jeep dealer, but the earliest is late next week.

Any suggestions?

 

Any engine code? This sounds like the throttle position sensor which is on the throttle body.

EDIT - I would disconnect the battery for a few minutes and see if that does it.

 

I agree with the battery disconnect. Check for codes as said since it seems like you may be in limp mode.

 

Thank you very much gentlemen.....Disconnecting the battery reset it and all is well!!!!

Thanks Again,
RWB

 

Good to hear that!
