Do most people bypass this valve or should i leave it connected. reason being after coming home fron work and left my car for about an hour i started it up and the idle stuck at 1500rpm!?! with no eml light on. could not find any vac leaks so i disconected the battery for about 30mins, and it was fine after. don't want it to happen again, it pi**ed me right off.
any idea's people
