ok so here's my problem, i have a misfire on cylinder 2. which is an understatement it barely ever fires so and i changed my spark plugs last night and oil. my wires are not that old and i have a H.O. coil packs. sometimes it will fire and run smooth for about 2 seconds, then back to being rough as hell. and i have autolight platinum plugs in right now. and im going to start at the plug then work my way aroud.

what did the plug look like when you pulled it?

plug is fine. i turned it on and pulled the wire from the plug on #2 didnt do anything. i pulled the wire on 4 and 6 and they sparked to the block. so it either coil or wire

Get a spray bottle filled with water and mist down the wires. If it sparks, its the wire. Its probably the wire. If it were the coil pack the cylinder next to it would be misfiring too.

well turns out it was the coil pack. i changed the wire and still nothing, didnt spark when i pulled it off the plug while the engine was running. but the only cylinder that was misfiring was #2 so thats why i never thought it was the coil but i replaced it and she's back to purring
