Multiple random misfires?? The other day when i started my car the exhaust popped. Now when im driving it, it misfires like crazy when its cold. worst in low rpms but does it at high in rpms also. once it is warmed up it doesn't do it as bad but it still misfires. when i ran the code it was PO300 Multiple random cylinder misfires detected. Where would i start to look to fix this problem. new plugs and wires were installed about 3 months ago and i dont believe its water in the gas (although thats what it acts like) because i added a bottle of heat and my problem is still there. any help will be appreciated. Thanks

Problem found. Broke plug wire #3 cylinder, where it plugs to the blaster pack, popped my hood in the dark and saw alittle blue spark shooting around and i checked it today and the connecting part of the wire was broken.
