Hi Guys, I just wanted to share something I have found that works on my JK Wrangler, A few weeks ago the Engine Management Light came on and the car went under powered and staggered when on the throddle.
After 2 weeks of stuffing around in the shed I have found how to reset the limp mode.
Under the hood,
1. Disconect NEG battery terminal.
2. Turn on ignition
3. Tap Neg Battery Lead onto terminal, (horn will sound, and wipers may
operate) you will hear various sounds of solinoids starting up.
4. Turn off ignition and reconnect terminal.
I have used this 3 times now and each time it works. I think limp mode does come on for some very lame reasons and maybe just a money maker so you have to need the dealer once more. Hope this helps a few people as many seem stuck by this so called LIMP MODE.
