BNaylor, will this issue always prompt a trouble code? I took the car in to the mechanic today to have it scanned. The car acted up half the trip there, but no DTC's were found. The mechanic used 2 different scanners to do it, one was Mastertech and one was a new one (Tech II ?). Neither scanner came up with any stored nor any pending DTC's.
I have an appt set up for Friday to get the PCS fixed, but if not having a trouble code may point to a different cause to my car's problems, then I can cancel my appt and have the car checked out further.
