Misfiring diesel - fixed

Recommended Posts

Rough idle, loss of power, intermittent loud pre-ignition rattle on hard acceleration. Various error codes including MAF, MAP, Rail pressure sensor. Improved on unplugging MAF, but still low power.

Replaced MAF and MAP,  checked for boost leaks, but was not fixed until we changed the fuel rail pressure sensor and cleared the 3F31 error.
