Cigar lighter/12V accessory plug, whatever you choose to call it.
Look under the hood and you will find a placard with this information listed. .42-.46 for 7.5L(460 ci)
you will need a 5/8 spark plug wrench let the engine cool, then disconnect the negative battery cable remove the spark plug wire from the first plug and remove and replace the plug dont forget to gap the new plugs between 42 and 46 and repeat on the next one be sure to only do 1 at a time as not to mess up the firing order
The gap is .017" to .023"Dwell angle is 41° to 46°Spark plug gap is .035"
i have a 1988 ford ranger xlt 4 cylinder and my spark size is 42-46 hope this will help
According to all-parts.com/diagnostics/mechanics/Ford_Mustang_GT.html, "If this is a 5.0 litre, I have the answer... And this one took a lot of hours to find.... The spark plugs have to be gapped at .52 to .54 on this..... Not the .42 to .46 like all the other Fords."
Bad coil pack or spark plugs...
Passenger side, front of engine.
Fuse # 47. It's fuse #46 not #47
