That there are no warning lights coming on when the problem occurs makes the diagnosis difficult. It could be a problem with the computer momentarily sending the transmission into “limp home” mode, but I would normally expect to see a warning light when that happened. Other than that I would check the fuel injectors, and although you say they were cleaned I would have them cleaned by sonic vibration out of the car. That way the spray can be checked before and after the clean. You could also check the spark plugs and make sure they have been changed as required. The rear plugs are platinum tipped, and it’s a bit of job to remove and replace them, the intake manifold has to be removed to do it and some people baulk at the cost.
That increase in fuel usage on E10 is in line with what we've been told would happen by the biofuels people.
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.
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.
Fighting your way through all the sales pitches to get the good information is always difficult and most tyre people will favour the brands they stock. Most retailers should be able to offer you a range of tyres, ranging in price from cheap to quite expensive and varying levels of performance. The Magna is a middle of the road model and I would go for a well-respected brand of tyre that has a tread pattern that offers good grip in the wet, rides comfortably and has a good prospect of wearing well. It also has to be the correct size, load and speed rating.
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.
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.
