K_C Ranger 04-27-08, 11:17 AM My money is one plugs and wires. figment3 04-27-08, 04:59 PM will change them out next sunday, and we will see,car has 117,000miles, but the look like they have been done already, not shure about the plugs, witch ones should i use?owners man calls for 41-900 is this right? Ranger 04-27-08, 08:01 PM 41-950 if I recall correctly. I think the wires are 748J. Check http://www.rockauto.com Glengemen 04-27-08, 11:18 PM P0300 is a random misfire code. If you had a consistant miss on a specific cylinder you would get a code such as P0302-cylinder #2 misfire. Like the others above I would say your wires are shot. They will probably OHM out fine (1K/ft) but they're not providing protection from electromagnetic interferance causing the ignition control modual to screw up causing a misfire. | |
