I was driving a little aggressively on the way home from work yesterday, hadn't done so in a while. When I pulled into my driveway the idle was rough, almost dying then coming back. I opened up the hood to check if any of the hoses had popped off and noticed the left hose on the pressure chamber had come off (when standing on the driver side of the car). The map sensor was ok. I plugged the hose back in and fired up the car again, but the idle was still rough. Anyone know what else could be wrong?

 

what are your mods?
how much boost are you running?

 

maby the information was stored in the computer, you should try resetting the ecu, by unplugging the negative cable for the battery and pressing the brake pedal for at least 30 sec, then reconnecting the cable. then double check all vaccum hoses again, hope this works

 

Only mod I have is a downpipe. Otherwise everything else is stock.
