well im hoping it will cure itself as the car sits overnight... but why would the RPM's surge only when the Intake is on.. and be fine with it off?? Just because its harder for the car to breathe with the intake on? The car drives normally... it just happens when the car is in P or N. The can did not say how much to spray... i had very little black carbon come out of the tail pipe... i was wanting/expecting more.... this has just seemed to be a waste. Im not doing anything else like this unless i know it needs to be done. h:]

Im thinking it will get better as the car sits... because when i was first experiencing this problem, it was constant as soon as the car was in P or N, or just sitting... now it only really happens when i mess with the gas pedal, trying to make the car do it.
