I recently installed a cold air intake on my 2009 Jetta mk v. And I’ve had it on for about 2-3 weeks now. I haven’t had a problem with it up to this point, I installed it correctly as the directions said. But, now it is beginning to misfire at high rpm and when it does, the check engine light blinks on, then goes off. I’m not sure what the problem could be. Any help would be greatly appreciated.
