Ross Tech Wiki says;
16688/P0304/000772 - Cylinder 4 Misfire Detected
Possible Causes
* Ignition system
* Fuel injectors
* Fuel pressure
* Running out of fuel
* EVAP canister purge valve
* Evaporative emission system
* Low compression
* Base engine problems
* Controle Module damaged
Special Notes
* This feature search for engine misfire in a specific cylinder. Most of the time the cause for a misfire is a lack of combustion in a cylinder due to absence of spark, poor fuel metering, or poor compression.
Disconnected No. 4 Coilpack and the engine made the same horrible lumpy noise, so this seems to suggest that this (coil pack) is buggered.
Comment/suggestions please.
