hi i have an 04 xfire manual 110k just before Xmas had sticky ignition so replaced ignition barrel & removed steering lock however since having it done the car starts & drives fine & seems to cut out once hot after approximately 20 min then won't even attempt to turn over like the immobiliser has kicked in & won't start for hrs at least 6-8! Has anyone experienced similar problems? Any info would help as stepdad who owns garage is tearing his hair out trying to find the problem!
