My car has thrown that a couple times over the years, just cleared it and doesn't come back on. Plugs/wires? P0300 can be a pain to diagnose without a scanner.

nothing really....exhaust..intake..msd cables...msd distributor and cap...i took i tto my mechanic the other day and he said he thinks its the wires..he said one one each side is bad...he said the wires might be touching the manifold or some other heat source..he's kinda old and has a bad back thats why he cant work on it...also...the exhaust shakes a lot too..both pipes...hmmmmm maybe also a bad o2 or maybe even the cat conv..went bad..i donno. i guess we'll just have to wait and see
