Bought a 09 370z nismo in Jan with a Stillen gen 3 intake. It has been throwing error code P0300 multi misfire in cylinder according to the dealer every time it rains, 6 times since Jan. Dealer thinks its a Intake issue and Stillen says its a vacuum leak or defective EGR. When I hammer on her from first to second she hesitates as though my foot is off the gas, then catches up and goes. Anyone else run into this issue? Tired of the damn check engine light turning on and the run around from the dealer. Should i take her to get tuned? Any help would be greatly appreciated!
