HELP -My 1997 C5 has random detonation- Car runs perfectly except occasionally engine will start to knock loudly at low speed and idle -
It sounds scary -like rod bearings rattling. Engine light illuminates and OBD scanner displays P108 MAP sensor high input -
After resetting , using the OBD scanner the car runs fine again when restarted .
Have checked MAP sensor, wiring, connectors grounds, and vacuum lines but everything seems OK- Any ideas?
