Morning - hope you are well. Not posted in a while as the Puma has been fine.
Over the past few weeks it has been stalling when pulling up to lights and running rough when idling. I have changed:
MAF sensor
ICV
No joy so have had it scanned. The following errors have come up:
>>>>
PO460:
Invalid fuel tank message from cluster
PO122:
Throttle Position Sensor low
P1381:
Variable Cam timing overadvanced, Bank A
I am told these are the possible causes of this last error code
Cam timing improperly set
No oil flow to piston chamber
Low oil Pressure
Solenoid valve stuck closed
Camshaft advance mechanism binding
>>>>
Any thoughts? I suspect only one of these is causing the issue, and most likely the last of these. I don't think the timing is improperly set - it was changed 5k ago and has been fine. I'd like to gather some insight prior to spending more cash. The only 'usual' thing I have not changed is the crankshaft position sensor - could that cause these issues?
Thanks in advance
Pauly
