slight miss/skip at idle no codes where do i go from here?
Hi I am looking for some advice and some help.... I posted this in trans issues before because that's what it seemed to be at first but here goes with my issue....
I noticed it when it was really loaded down with firewood. It seemed to be hopping or pulling when I was at a stop light and rolling just off idle. It made the truck almost bounce as I was pulling away. It gets 16 mpg no matter how I drive it, it pulls hard and I would never say it lacks power. I have no codes, no check engine light, etc. Fuel and air filter changed less than 500 miles ago. Oil is right about 5000 miles on rotella 5-40. I plan to change it between now and 6000 miles and have a blackstone oil analysis done on it. My issue happens when flashed with superchips and when not, nothing seems to affect it. I keep reading about a buzz test and cyl contribution test, I don't have the means of running those right now, but I may in the future. It doesn't run bad enough to even dream that its a bad injector, but this my first stroke, but far from my first diesel troubleshooting situation <VW, mercedes, detroit, cat, cummins, gm all in my past> I keep reading about the UVC harness and how that can make for issues like this. Do I dare tear in there and check for a loose one? Do these things normally throw a code when they miss bad enough or does it take a lot? How much of a pita is it to pull the valve covers and is this where I should begin? Maybe its the hpop oil that hasn't been changed....lol. is is worth my time to get a buzz test and cyl contribution test done? How much should a shop charge me for this? Thanks. I'm going to try and put a video up of it running. Maybe that will help. - Scott
