Thanks for the advice guys, I think I am going to call K&N and Fitch. I want to try other things before removing Fitch. The fuel line had to be cut to add Fitch so I will have to buy another fuel line to take Fitch off. I see all of you say it is the Fitch but my mechanic friend says his buddy's Corvette does the same thing and it is the K&N Air Intake causing it. If we can't solve the problem I will take one of them off.
