Ok thnx guys, im off to the cabine tomorrow so im gona break it down and clean/lube..se if it helps.
I also went by the dealer today and had them order a new pressureswitch..warranty is running out this month so I figured I give them one more thing(airbox blew up last summer) to fix for me under warranty :-)
