Consumer Description

The engine burns Coolant and yet doesn't overheat. The engine on cyl 4 misfires. Changing the head gasket didn't repair the issue, replacing all fuel Injectors and ignition parts didn't either. Heads inspected and passed. Compression testing passed. Always misfires on cyl 4. No repair aside from an ecu reflash or replacement seems to be possible. 4 shops looks at it and couldn't find any reason why it was misfiring and no traces of water were found in the interior, on the floor, in the oil or exhaust in the cooling system.
