Mitsubishi Magna Problems

1500 kg when the trailer has brakes.

Any of the quality brands would perform well on the Magna. IMPCO made the air-valve system used by Mitsubishi on the cars supplied from the factory with LPG. It’s generally regarded as bulletproof, so that’s certainly one to consider.

After David McKenzie told us that his TJ Mitsubishi Magna used up   to 40 per cent more fuel when running on E10 than it did on regular   unleaded we felt we should refer it to the experts, as his experience   contradicted the advice we had received about the fuel. David's   experience confounded the experts who said it went against everything   they knew about the fuel. They told us that Mitsubishi had no   problems with the TJ Magna using E10. Further we were told that   providing the oxygen sensors were working correctly the engine   management system on the Magna would adjust for any changes in the   fuel. It was suggested that David have the fuel-injection system in   his car checked by a competent mechanic.

The biofuels people told us that the fuel consumption would increase by up to three per cent on E10, but your experience certainly makes us question that. Perhaps other readers can let us know what they've experienced when they've used E10.

There's very little engine braking available with an automatic transmission, and with the desire to achieve the best possible fuel economy there have been changes to the transmissions, gearing, torque converters etc. that have further reduced the effect.

Unfortunately the old Magna was known to suffer from idle shake when stationary and in gear, and there's not a lot you can do to get rid of it. Owners often put it into neutral to overcome it instead of leaving it in gear at traffic lights etc. As for the hunting in gear you could check the throttle position sensor and make sure that is adjusted correctly.
