I was driving up the road yesterday and my truck just lost power. It still runs but it runs rough almost like it isnt hitting on all cylinders. I still have decent fuel pressure to the vp and I dont have any codes. I have unhooked my tst and used the superchips tuner to go back to stock programing. I pulled the valve cover to make sure that I didnt bend a pushrod or something but everything is ok there. There is no signs of a blown head gaskes either. Im not sure what to check next. Do you think my vp just took a crap? It has 141,000 miles on it. Any help would be greatly appreciated. Also how do I do a compression check on a 24v?

 

Any 24v guys on here tonight?

 

What happened when you lost power, did you step on the go pedal and not get any response? I had a Vp crap out on mine even with a FASS hooked up.

 

He said he checked for codes and did not have any, but i have read that the vp code does not always show up. If he has an Autozone near by, he can swing in and they will scan it for free and he can write down any codes if he has them

 

I was on the go pedal while going up hill when it lost power. I checked for codes with a scanner and got none. Do you think its my vp? also is there a way to check for compresson on these motors.
