This all started about a week and a half ago. I have read and read on here about people with similar problems, but nothing really the exact same.
The truck seems to stutter when going up a hill and just as it crests the hill, its worse when the cruise is set, and it only seems to do it when going 50+. It also seems to be down on power until it gets good and hot. This usually only lasts through the first 5 or 10 minutes of driving.
Once the truck is good an hot, it gets all its power back, and the stutter goes away for the most part. The only time I can hear/feel the stumble when the truck is hot is when its idling. At idle it sound kinda like its missing.
I also get a little white/gray smoke when starting it cold (sitting for more than 6 hours)
Today I changed the oil, replaced both fuel filters and cleaned the egr valve. The truck gained a lot of power back, but the stutter is still as bad as ever on the highway.
My next guess is that I might have an injector trying to go bad
Anyone have a clue? I was betting on the EGR valve, but cleaning it didn't help at all...
