Check tire pressure and correct with falling temperatures.
Tighen hose clamps, there are MANY! Also the hoses at the reserviour.
Check for dragging brakes. Jack up and turn. Or coast ( do not touch the brakes!) to a stop on a highway run then feel the rotors. They should be relatively cold. Check for any 'warmer' than the others. That could indicate warmth from brake friction. Coasting to a stop on an uphill section will get you to a stop much faster.
You do need to be resetting the SID on highway runs, after a good warmup, to get good comparative repeatable figures.
You should be using NGK BCPR6ES11's. Sounds like you are running an incorrect or cold spark plug. Gap to .035" Spec is 1mm, -.2 +.1, so .035 in nicely in the range and provides for better useful plug life than .039".
Clean your injectors. Suggest Techron Concentrate. Use this every 8K miles or 2 or 3 times per year. If you have not done so before, do two concutive treated tanks of fuel. I assume that you are in Canada. You will not get Techron there. Get another brand of 'fuel system cleaner'. Basic injector cleaner is not the same. Try CTC.
Do you feel any ignition misses? If so, after the techron and possible plugs, then your DI could be failing.
Is your temperature indicator at 9 o'clock or lower? If lower, you need a new thermostat and your engine is running cold.
If you do lots of cold starts and short trips your plugs will get fouled.
Does the CEL light come on before you crank the the engine to start? Does you low oil pressure warning light also show during this 'lamp check'.
