Got in a pretty bad wreck about a month ago which screwed up a lot of things under the hood. I got it back from the show a week and a half ago and automatically noticed a power loss. Tonight when I got off from work the jeep wouldn't start, the throttle just clicked once. After about ten minutes of trying it did the same thing. While I was trying to turn it on my check engine light and electronic throttle control lights were on. At first I thought it was the battery but my stereo was working as well as my lights. Finally I got it to run but a really deep roar came out of my engine which was my throttle. Anyone know what's going on with the loss of power and both those lights being on? I need help ASAP.

 

Did you have any repairs done to the wiring harness. If the mechanics had to bypass and splice some wires, there might be a faulty connection somewhere that keeps throwing everything off... That's my guess, hard to say anything else unless you know what repairs you had to get...

 

Alright cool, idk what all they did but I'll talk to them tomorrow and see if that could be the problem

 

Batteries can go bad from accidents. The internal plates could be touching which would cause an intermittent voltage loss. It can be tough to diagnose.

 

Try a new battery, dipshits at a shop drained mine, then used a jump box to start it up a few times. They did not tell me anything(called them) until I got about 5miles away and all kinda weird electrical shit happened. Stopped and it wouldn't crank. I put a new battery in, cleared the codes, no probs after that. If these jk's don't run the right amount of voltage, they go stupid.
