I've been having stuttering/brief loss of power. This has been going on for a while, and nobody can figure it out. The car isn't throwing any codes. My mechanic (good for him, sort of) doesn't want to just start throwing parts and time at it without some diagnostic. He drove with me with his (Snap On Tools) scanner hooked up, but the car didn't do it while he was driving with me. This trouble is worse when it's warm, and worse after the engine has had a heat soak, like after parking while running errands.
The problem shows up with a short loss of power, like I hit a mud puddle, or sometimes a few mud puddles, and then it drives normally after that.
So I just got the OBDeleven so I could explore for myself. I've only looked for stored faults and run it while in the driveway. There were no stored engine faults. I did get one misfire on cylinder 2 per 1000 revolutions while in the driveway. I also looked at my Timing Chain (Camshaft Adaptation Bank 1, phase position) and I get -3, which I understand is a bit sketchy but not catastrophic.
I'll look for misfires next time I'm driving. But what else should I look for? Can I look at turbo values, pressures, etc? What

I think I solved it. I drove with live data looking for misfires. Indeed, they were all zero, then after the stutter I had misfires on cylinders 1 and 2. Every time. Plugs and coils for those two.
