Thanks for the help. I have the mopar slush mats so will move them. And yes as soon as the accelarator got stuck I put it into natural and combined with braking it stopped the car. Then I turned it off at the key. Then it wouldn't start for a few goes. My mate was with me and said to jiggle the 4wd leaver. Then it started and has been fine since.

Here's what the Drive by Wire looks like

Actually that's pretty much what NASA came up with that caused the Toyota sticking gas Pedal problem. They found what is called, Tin Whiskers, tiny micro size metal that formed a link to the sensors for reason that computer didn't react to programmed action of stuck pedal...so I'm sure it wouldn't be hard for these parts to do that either...

Anyone see this yet? It has to do with Floor Covers and Accelerator:

Recent 2008 Wrangler Recalls

  • EQUIPMENT Recall for 2008 Jeep Wrangler
    • Recall Announced FEBRUARY 25 2013
    • NHTSA Reference #13E010000
    • Number Affected 15,836
    Summary: Quadratec, Inc. Is recalling certain aftermarket accessory, driver-side, ultimate floor liners part numbers 14254.0301 07, 14254.0301 08, 14254.0301Q, 14254.0302 07, 14254.0302 08, 14254.0302Q, 14254.0303 07, 14254.0303 08, 14254.0303Q, 14254.0309 07, 14254.0309 08, and 14254.0309Q sold from May 1, 2012, through February 14, 2013. The liners are for use in 2007-2013 Jeep Wranglers. The anchor point for the affected floor liners may tear during use, particularly when exposed to high temperatures. The tearing may allow the floor liner to shift forward.
    Consequence: If the liner shifts forward it may impede the operation of the accelerator and possibly lead to unintended acceleration, which may increase the risk of a crash.
    Fix: Quadratec will notify owners and either exchange the liners or provide them with a hook guard kit to help secure the driver-side mat, free of charge. The recall is expected to begin in March 2013. Owners may contact quadratec at 1-800-463-2998 or info@quadratec. Com.
    For detailed information & supporting documents, see the official NHTSA page concerning recall #13E010000 »

Ahh, memories. Sometimes I miss the simple things.
