Vectra B - P0354 Error Code - ac427 - 30-09-2015
The crank and cam sensors have been replaced plus a new coil pack.
Sadly the error code P0354 has returned.
The car starts first time and idles well but after a few minutes the idle becomes lumpy.
OP-Com reports the battery voltage is 14v.
Do the alternator voltage regulators go wrong much on these cars ?
Why would the ECU only shutdown cylinder 4 though ?
