Help..misfire on one cylinder and tried everything
Help..misfire on one cylinder and tried everything Ok...here is the cliffsnotes version
05 Chev. SSR 6.0 liter
Installed magnacharger with supplied injectors and harness. I have a random misfire in cylinder 6 all of the time at idle, but it goes away under load when driving and at full throttle. Here is what I have tried.
1.new plugs
2.swapped wires
3.swapped coil packs
4.swapped injectors
5.swapped injector extensions
6.sprayed for vacuum leaks with water, and carb cleaner (nothing)
Long term fuel trims for bank 1 and 2 are at +8...O2 sensors are functioning properly, Maf is functioning properly...desired idle and actual are good... what else can I check?

look at the stft and ltft bank 2 while spraying it. if you can pull up a custom data screen for that it will help by speeding up the refresh rate big time. a leak is what i'm thinking you covered the obvious. any freeze frame?
