keep dropping a cylinder

[wyomoose]

ive got a 13 pro with the RK tech 858 kit in it. I keep losing the mag side cylinder after about 3 to 4 miles, stop put new plug in it and it goes great for another 3 to 4 miles, the compression is good, changed to several different fuel maps from lean to rich doesnt seem to matter.. any ideas????

Did you check ur piston to cylinder clearance??? I pretty sure it will be of... It should be within 4-6k of an inch

It sounds like your fouling that plug, maybe an injector?

Did you have your injectors checked?

What does piston wash look like?

switch your coil/sparkplug leads, injectors etc etc...and see if the issue travels to other side when you swap a component..

Check injectors and check your coils/coil wiring maybe.
