I have got a 2006 Jeep wrangler x . Its got 6,000 miles on it. I was wondering if anyone could help me . Im having some mechancial problems with it . I've had in the shop 3 times. The first time they said is was the trottle postion censor. The second time is was the same thing, now its got lose of power and grinding going in reverse. Grant i have taken in it mudding 2 times. Its bone stock height but I didnt smurge it . I dont understand whats wrong . when u come to a redlight it got a little shake to it . its quit before . I bought it with 3 miles on it . its a 6speed , with the inline 6 in it . I would like some good advice on what i can do to fix it ! thanks cassidy

 

Since it is still under warranty I'd take it to the shop. A DIFFERENT dealership than where you have already taken it, though. Give a different shop a crack at finding the real problem.

 

check your "Lemon Law " paperwork it may still be covered and it sounds like it meets the three returns policy

 

Is the check engine light on? it could be the crank sensor or an oxygen sensor, I've seen both cause simular problems, but both of these should through a code.
I'd agree with FiveOFF take it to another dealership and if you have mud in the engine compartment I'd GENTLY wash it out with a garden hose (power washers can do to much damage) before you take it in.

 

Ditto and ditto.
