Rough sputtery idle ✅ Solved
My Jetta has a sputter when idling in park. I don’t know what’s up. Car has 272Ks
I just replaced the spark plugs. Additional info: Sometimes when I start the car (Cold) and turn it off around 1 minute later, it has a significant rough idle the next time I start it.
Maybe I need new ignition coils?

I corrected this issue by adding some Lucas injector cleaner into my gas tank. Injector in cylinder 5 must have been clogged (cyl 5 threw a misfire code before).
Does your jetta have an idle air control valve?
