Well out of the blue my truck acted up yesterday. Had to crank longer than usual to start it and then it had a slight rough idle and really missed bad with just a little throttle on it. So I cut it off, tried again and same thing. Drove it back home about 50 miles and runs fine and doesn't miss once you get going. Got home, cut it off and takes more cranks before it will fire off.
I'm thinking injectors. So far I've checked and fuel pump is running, all 3 fuel filters only have 7,000 miles on them. Not making any oil, no codes, CP3 is acting normal.
Here's what I'm gonna try and open to suggestions:
Run a heavy dose of injector cleaner
Pull valve cover and run to see if a injector body is cracked
Drain WIF on both filters and inspect catridge filter
Last option pull injectors and send for testing.
