In the next few days put a new turbo in (rebuild) $1850 truck drove ok for 2 days, then it start loosing power again (the same thing) going on for 50 miles then loose power = can't go more then 45MPH then in 10 miles normal again. Stopped at the frei dealer they tech looked at it, said you have a air to air leak. Spent $1200 plus labor, drove 20 min the same thing.

wonderdog24 you think it has something to do with batteries or ECM?

 

would the injector cut the whole power like that???

 

Hi, this is not just everyones in a while it comes and goes all the time. It will drive good for 20 miles and then no power again.. I would think the injector will be bad all the time, no? I drove the CAT with bad injector it was running extreamly rough and had a miss fire feeling, in this citation there is not missfire.
