Mitsubishi Convertible Range

Running on after the ignition is switched off is more of a problem in petrol engines than diesels. But you haven’t told me which engine your Triton has, so maybe it’s the 2.4-litre petrol we’re dealing with here. If so, you may find that the running-on is being caused by poorly timed ignition which could suggest a problem with the physical bits that make up the ignition system, or even a problem with the computer that controls it all. Worn or leaking fuel injectors could also cause this problem.

If your engine is the turbo-diesel, then another potential cause of running on is a worn or stretched timing chain (the petrol engine uses a toothed timing belt which shouldn’t stretch) that has allowed the camshaft to get slightly out of phase with the crankshaft. In both these cases, the fault could easily be enough to trigger the check-engine light and keep it on to alert you to the problem. Have the vehicle scanned to see if there’s an ignition fault or what’s called a camshaft deviation, indicating a worn timing chain.

Yes you can. According to the Federal Chamber of Automotive Industry’s guide, all Australian-delivered Mitsubishis with fuel-injected petrol engines built after 1986 can use either E5 (five per cent ethanol) or E10 (10 per cent) safely. By using this fuel, you stand to reduce your tailpipe emissions a little, use a percentage of renewable fuel (ethanol is largely made from farmed crops) and you may even save a few dollars over a year as E10 ULP is often a little cheaper at the pump.

Yes, it was fitted with an engine immobiliser from the factory.
