What does a Misfire feel like?
Hey guys, I am running the Cobb tune, with BMS intake and upgraded downpipes.
Lately, under boost, It will feel like a couple hard studders while accelerating. especially in 4th gear. Also while idle, itll be smooth, with an occasional small burp. No codes. WTF is going on?
I ordered new plugs, hope that helps!
Is this common?
