04' LS V6 Not firing on 1 Cylinder
About 100 miles from home the engine began to run really bad. It shakes like a monster, and on the way home it would randomly go into safe mode and all I could do was shut it off and try again.
Anyway... I found it it's the middle cylinder on the drivers side. I swapped out coil packs, changed the plug again, and it still doesn't seem to be firing. The plug/coil both have spark. No oil is leaking at all.
Anyone have any ideas? I'm about to rent a scanner and hopefully a compression tester.
