Hello,
My 'check engine' light came on and during stops, my ST felt like it was going to stall. The mechanic said it had a vacuum leak and got codes of PO171 and PO174. He showed me the 'Crankcase Ventilation Valve Tube' and it had a rip on one of the soft ends. He replaced the part, but now my ST completely stalled 3 times (it never stalled before the replacement). It stalled at a stop light, during a slow turn and when coming to stop on my driveway.
Has anyone experienced this problem? If it's not a vacuum leak, what could it be? Thanks!
