My truck in my sig and a customers truck both are now experiencing a hickup driving down the road. Does not matter if your heavy on throttle or light on it. Almost feels like a gas motor with a plug wire that is breaking down. I have been running Power Service in every tank sense I bought it. Any ideas???

 

Anyone?????

 

Are you getting this with a low amount of fuel in the tank? Inhaling air maybe?
Any codes?

 

No codes. Fuel pressure never drops below 17 psi. It dont matter if it is full or at a 1/4 of tank. It still does it.

 

I dont know if this will help but I was having that prblm with my 2005 3500. It would mostly hic-up when I returned my foot to the throttle after coasting or after a stop light when I would step on it it would hic-up. Only for a second and then I it had all the power I needed. I took it to the dealer and they replaced my lift pump and my injector pump. But I still have the prblm. So I think it is my injectors. Just letting you know that you might want to start with testing injectors. And just a thought, start with changing your air filter and fuel filter. It is amazing what effect they have on things like that.

 

My truck has gone thru this several times.
What I found is the battery posts are corroded. Fixed it every time by cleaning them.
It is like a random misfire, very low on power too. wouldn't even go 40-45 mph.

 

sounds electrical to me..

 

Ill start with resetting the apps and cleaning the battery cables. It got so bad yesterday that I was afraid to pull at Chestertowns Pull that I was heading to. Thanks alot.
