If I could fix one thing on the JK, this would be it! My I-6 258 CJ pulls nicely from idle while my '11 JK 6 speed will either flat stall, or sputter sub-idle for several seconds before dying. I know revving more during starts works, just not my driving style. Interested how this pans out for you.
WELL,,,,,,,,,,,,,,,,,,,,,,,,, AFTER THREE YEARS of hating my JK's inability to pull off from a stop,,,, All I can say after I picked it up an hour ago is AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH H
IT IS SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO much better. I tried to stall it and it didn't stall.
A damn PCV caused all those issues. I also got 24.3 MPG on the 40 min drive back home.
That about 2 MPG better that I usually get on the highway.
I wasn't able to speak with the service manager because the service department was closed on Saturday.
YES,,,,, THAT WAS THE ISSUE and I AM SO GLAD its resolved!!
The new PCV Part number is: 4648973AD (corrected number)
I will speak to the Service manager on Monday and get the info on the TSB. Its deals with Throttle Body repair.
