JUST FOR GIGGLES

YOU MIGHT FOLLOW #5 WIRE--LOOK FOR IT TO BE AGAINST SOMETHING AND HAS RUBBED A SORE SPOT IN IT

IT MAY BE ARCING AT THAT LOCATION---USUALLY YOU WILL SEE A GRAYISH POWDERY SPOT RIGHT THERE AT THAT POINT (IF SO, IT'S TIME FOR SOME WIRES)

WHEN I'VE COME ACROSS THIS PROBLEM, AFTER INSTALLING NEW WIRES, I'LL TAKE SOME 3/8" OR SO TUBING, CUT ME A 3-4 INCH PIECE AND SPLIT IT, THEN POP IT OVER THE WIRE AT THAT POINT. I'LL NOT ONLY "PROTECT" THAT SPOT, BUT ANY OTHER PLACES THAT COULD RUB IN THE FUTURE, ON THE OTHER WIRES

WELL, LET'S SAY, ALL WAS GOOD ABOVELET'S SWAP #5 WIRE WITH ANOTHER WIRE (I MEAN COMPLETELY SWAP THE ENTIRE WIRE, NOT JUST THE PLUG END OR THE COIL END) THE WIRES MUST TAKE EACH OTHERS PLACE! NOW THEN, ARE WE MISFIRING ON THE CYLINDER THAT NOW HAS THE PREVIOUS #5 WIRE.....IF SO, AGAIN, HE WIRE IS BAD!

OTHER STUFF CAN CAUSE A MISFIRE TOOSPARK PLUGS----INJECTORSCOIL----EVEN MECHANICALLY, VALVES

THE BESTUS THING YOU CAN DO IS CATCH UP ON THAT PESKY PREVENTATIVE MAINTENANCEYOU KNOW, THAT STUFF YOU SHOULD DO/ REPLACE/ CHANGE FLUIDS/ INSPECT/ CHECK!

DOING THIS ALONE............MAY SOLVE THIS PROBLEM........WON'T HURT ANYWAY, YOU SHOULDA BEEN DOING IT ALL ALONG!

WHILE I'M PREACHING (AND THERE'S NO EXCUSE...LIKE I DON'T HAVE ONE!) MOST ALL OWNER'S MANUALS PRESCRIBE CHECKING YOUR OIL AND WATER ONCE A WEEK......ANYTHING DEVASTATING COULD HAPPEN, EVEN BEFORE A WEEK'S TIME, YOU MIGHT CATCH A PROBLEM IN TIME AND SAVE YOUR ENGINE!

A GOOD BIT OF THIS STUFF CAN BE DONE DIY!................YOU JUST NEED A LITTLE SHOVE/ A FEW TOOLS/ THE ABILITY TO READ AND FOLLOW DIRECTIONS/.........AND ABOUT $30!
