Greetings,

Has anyone ever had any revving issues at start up?

I have a 2001 and twice now when I tried to start it, it revs to red line (by iteself), then shuts off and will not restart. After allowing it to sit over night, it starts like nothing was ever wrong and drives for a few thousand miles without any troubles.

I had this issue before installing the FASS and Juice/Attitude.

Any advice would be appreciated.

Thanks

Never heard of this one. Maybe the injectors are sticking?? Fuel additive may help to lube those injectors. Dang ULSD.

I had that issue.. After further inspection I found a little tiny man that hides under my dash and smahes my pedal down to the ground. I finally set a little trap and caught the little sucker and let him go back out in the wild.. GL

Just messing, never heard of that but I'm almost sure someone with much more sense then me will chime in.

Not sure on codes. No lights on the dash, but I haven't taken it anywhere and don't have a scanner. Someone said the Smarty works as a scanner too...might be in the market for one soon.

Also, the injectors are are less than 2 months old and the same thing occurred with the old injectors.

thanks
