04' A4, sometimes when I go to crank it up the rpm will go to 1000, then the car will shut off. It takes about 3 times to start, and on the last start it goes to 1500 rpm sits for a sec, then back down to where it's suppose to be. Also, it seems to bog down when i start from a light, kinda wants to die, then picks up, misfire? One more thing, when i floor it, the rpm shoot up, then a sec later the car takes off. Anyone else have this problem, or know how to rid it? No ses light. Only mods are new era intake, and slp loudmouth II exhaust. Thanks guys.
