My 20002 Saturn runs rough. The code I get is p0304. I have read what others say the problem is; one says its the rings and I need a major overhaul and another says it is in the throttle. My thought is that its the spark plug, wire or coil pak. I want a few more thoughts so I can track my problem down thanks

 

Well, how many miles on your '02? You're correct that the error code suggests a spark plug or coil pak or wiring problem. If the plugs need replacing, go for new wires too.

 

try the plugs and wires first per OA -- we'll see where it leads
