? boost leak ? check your vacuum lines, and if there aren't any holes, take it to the dealer

i just took my car to the dealer bc it lost alot of power not quite like yours but it went from 11 to12 lbs of boost to 5 lbs of boost and they told me it was the BPV bypass valve........... some say it could be caused by ur cat gettin clogged, cracked vacum lines airfilter stopped up, belt slippin etc i dunno take it to the dealer if u have warranty....

i dont think its a vacum line b/c on the way home it kicked in out of no where and worked right for about 3 mins then it kicked out and it still wont work right i guess ill call the dealer ship tommarow

bypass valve probably. sound expensive for the dealer to fix. i hope you've got a warranty

craigk_c19

yeah i have waranty b/c about 1,000 miles ago the car had a lose timing belt and the warranty paid to have that fixed so i hope it will get this fixed too!!
