Re: 05 gc 5.7
Thought I'd update this post. New fuel pump solved the hard starting and misfire. I then changed egr, pcv, all fluids in driveline. I've programmed it with the super tuner using the 87 octane program. It is running great now, no lugging or surging at all. Now if I can figure out the p0441 code I'll be happy. I also replaced shocks and struts with Monroe reflex in the front and I believe the sensatracs in the rear. Next up is stabilizer bushings. To be continued......
