It's probably detonating. You need to have the ignition timing checked/sorted. If you leave it too long? You'll melt holes in the pistons if it's bad enough. XB Fairmont sedan : [email protected] |

Was it missing or rattling? If rattling, was it the engine or did it feel more like another part of the cars drivetrain? Could be something easy like timing or it could be something else. Need to narrow it down a smidge.

It could be the timing chain on its way out

Yes it can happen out of the blue. The mechanical advance or vac advance unit can jam. [edit]I can also be caused by water leaking in to the cylinder via the head gasket. XB Fairmont sedan : [email protected]Edited by user Wednesday, 3 January 2007 1:31:53 AM(UTC)
