Engine Shudder... :(

I just installed the K&N Gen. II FIPK cai on my '03 gt and I've noticed a slight engine shudder when I sit in idle. Could this intake have caused the air in my engine to not mix correctly?

RE: Engine Shudder... :(

It should be fine. Check all your connections. Sounds like you may have a slight vacuum leak somewhere. It will mix fine with any CAI. The air/fuel mixture can't be the problem.
