Did you get new plugs and wires as part of the original service? If they got the wires out of sequence I'd guess it could explain the troubles. Bucking and backfiring noises from firing out of sequence (could maybe explain the "engine trying to start backwards" comment they gave you
), and the gas soaked plugs from the tech unsucessfully trying to start it?
Or did they maybe do an oil change and try and start it with no oil (I've seen that before when I worked at an Instant Oil Change in college). Would sound VERY bad with no oil pressure, but wouldn't really explain the gas soaked plugs.
