Occasional Sluggish Starts
My 2015 RDX occasionally has a bit of a time starting. I press the brakes, push the button, the starter motor engages the engine, the engine fires, but doesn't seem to catch on. It just fires with the engine run by the starter motor (it seems). This goes on for up to 5 seconds, then engages on its own.
Due to gas prices, I have (now and then) bought gas with 88-89 octane, not the 90+ premium stuff I normally use. Could the lower octane be the cause, not getting enough of a bang to self-start?
