Re: Help wanted: 90q fault code interpretation
See if you can read the ECU's part number. The ignition system is
completely different between CA cars and 49 state cars and none of the
parts of one type can be mixed with parts of the other (so says mr
bentley). This is detailed (if memory serves) in either the general info
section or the CIS section of the bentley....
