I have a 2004 GMC and for some reason i cant seem to figure out it has a surge when setting at idle and also when im setting at a light the truck wants to move when im on the brake. WTH is the problem no one around here seems to know
I have the same problem and was told it was the fuel pressure regualtor as well. I haven't changed it yet though. When I started asking for prices I was told $450 for one. Can some one point to exactly what is needed?
Yep its the fpr mine does it, been doin it for about 6 months now lol but you can also run 2 stroke oil or an diesel additive and it will fix it for about a week or so sometimes longer but wont fix it for good I think it sounds pretty cool while in idle
