My truck has 130,000 on it and Im getting contribution code on cyl 1 so im replacing the injector. While im in there also doing the egr delete since im slowly loosing coolant. Hoping its a leaky egr cooler. While im in there what else do i need to do.
Also, the p0088 code when cleared doesn't come right back. Do i have a faulty hpfb or can the injector cause this to throw a code sometimes. Truck runs fine with good power. Ive done the dpf delete and running a spartan tune since about 65000 miles.
Also..if i have to do a hpfp would it be a good time to do a down pipe and would it be beneficial. Right now i just have a dpf/cat delete pipe on the truck.
Any advice would be helpful. Thanks
Have you checked to make sure you aren't getting coolant or fuel in your oil? Have you hooked your truck up to IDS. Do you know how far off this cylinder is? Be careful with this one, a contribution code could always be from a cracked piston (which is fairly common on a tuned 6.4). Have checked for excessive blow-by? A cracked head could cause a contribution code although it is not the most common reason....that could explain your coolant loss too. A cracked block could also do this and cylinder 1 is where most of them crack.
A sticking injector is definitely a big concern because of the potential to melt the piston. I am not trying to scare you...I am just giving you some worst case scenarios.
