Did she add a programmer or something? If she hasn't been messing with anything like that she probably get it checked out asap esp. if she really is losing power. Mine says that for a second after I installed the Hypertech programmer but I was told it was normal.

disconnect battery for a few seconds, rehook up....should clear it.

 

[TEXAS DEMON]

thanks. she doesnt have a programer. i will do the battery thing.
thanks again.

mine did it several times when the HIDs shocked the system on start up. I just did the battery thing, reset and rocked on.

If it does it again, see if it sends any codes.

i'm curious - did that end up solving the problem?

If that didn't fix it I would start by cleaning the throttle body.

 

[TEXAS DEMON]

well the dealership said the same thing abouth the throtlebodyis full of carbon. and they also said thathe spark plugs that i used bosch double platrinum, arent compatible with the truck. i believe the throlttel body thing but the spark plugs?

 

[blueflamed03]

could, I have heard the E3 plugs giving codes and issues...so yes, I could see that.
