Like the title says, I have a 01 SSEI, with 140k miles. There is no SES light on.Car runs good at idle, no misses, runs good on the highway. The problem is that when I come off of idle, it stutters when you first mash the pedal, it happens whether you are in gear, or in park. I can power brake the car, and it does the same think, misses coming off of idle, but clears up after it gets past a certain point. Car had a SES light on when I bought it 3 weeks ago, the upper intake gasket was blown out under the supercharger snout. I did not have the miss before I changed the intake gasket. maybe it could be a vacuum leak somewhere?
