The VY oil cooler is in the radiator and is generally trouble free, but the guys at AW Automatics recommend an external cooler for all towing applications.
You need to have a diagnostic checker run over the engine to know if the oxygen sensor is playing up. Before you do anything drain the fuel from the tank, put fresh fuel in the car and take it for an extended run.
There have been thousands of Commodores converted to LPG without any problems, so there’s no reason why yours shouldn’t also run well on gas. Take it back to the installer; it’s his responsibility to get it running properly. If you don’t have success doing that contact the manufacturer of the system he’s fitted to your car and ask for their help in resolving the problem. If you didn’t want to go back to the installer find another one who works with the same system and go to them.
There are a number of things that could be causing the problem; you really need to get it to a mechanic the next time it happens. It could be the ignition coils, the crank angle sensor, the fuel pump or blocked injectors.
The Ecotec engine will be fine on LPG, many thousands have been converted. My preference would be for the injection system, it runs better, is more reliable, less prone to backfiring, and delivers the savings you want. But that said the older venturi/mixer system also works fine. Both Impco and Emer are respected brands. If you want to get more info on them talk to other owners who have had those systems installed.
Good to know if the plastic trim breaks on your Commodore. If it does, look deeper and have the dealer replace the foam as well as the plastic trim you can see. I’d say the real reason that they don’t change the foam is that it’s an expensive exercise, and nothing to do with the GFC.
The issues around the functionality of certain Nokia phones are not isolated to our system. But we are working with Nokia to improve the compatibility of their systems with our vehicle infotainment.
Have a mechanic do a leak check on the head gasket to see if it isn’t leaking there.
From what we’ve been told there is no such thing as Dexron XI, so we’re not sure what oil has been used in your car. Dexron III is available and that’s the recommended oil, and Andrew at AW Automatics has told us that it’s still the oil to use.
