Vehicle is a 2012 Jetta GLi - 2 liter turbo
I'm getting a P0301 code - misfire on cylinder 1
Only I never noticed it while driving. Just now however, after getting the code read and doing an oil change, sure enough it started idling rough.
Add some throttle, or get it under load and voila! Nice and smooth again.
This doesn't sound like coilpack or a plug issue to me, as generally don't those issues get worse under load?
Clogged injector maybe?
I'm thinking about swapping the coilpack from cyl 1 to a different cylinder to see if the problem moves with the pack.
Other thoughts?
