run some basic fuel injector cleaner, make sure your plug is gapped correctly, get a new cap and rotor also, reset the ecu, get back to us.

Hey there.

I am having the same problem, except mine is cylinder #3. My problem is that I got a bad tank of gas (others from the station had the same issue). I put in a bottle of drygas and some STP gas treatment. The light hasnt come back on again, and there is still some hesitation when I open it up.

Hope this helps.

93 Octane will definitely not hurt your car. It will just hurt your wallet at this point more than anything else. The higher the octane the greater the resistance to self ignition, so the less the chance of a misfire. Put in some new fresh fuel, and some water remover to treat the old stuff and see what happens.
