GT motor control system failure
Daughters car threw a warning light this morning. Engine management light basically. Dash says motor control system failure . It drives OK to me but obviously not right.
Car has a big bore throaty exhaust fitted and she said she thought it may have been blowing a bit recently. Is it possible that and the hot weather has taken the system out of the parameters. Ove red by the management system computer?
I cleaned the maf with the correct spray and disconnected the battery for twenty minutes to reset the Ecu to no avail.
Any suggestions as to where I should start looking for the cause of the fault? I don't have a fault code reader unfortunately. Thanks, John.
