ok...i didnt change my plug wires cuz they look good and they arent cracked or stiff or damaged...but i still have this low end stumble...at night i went undr there and checkby the opti where the plug boots snap in and was looking for some arching...but there was nothing....a friend of mine that i work with, he said to get some salt water, and a spray bottle....put the nozzle so that its a very very very fine mis...ad just mist it, THEN WHEN I DID IT, ALL OF A SUDDEN I SEEN ALL THE BAD SPOTS....im gonna change wires tomorrow to see if thats the problem...

my only qustion is....if yu cant seethe arching wouldnt they be good? the only reason why its arching more with salt water is cuz its conducting but im gonna try this...hope this helps, plus DONT DOUCHE THE OPTI SPARK JUST THE WIRES, THEY WILL ARCH CUZ THEY AR CLOSE TO THE BLOCK AND STUFF, HOPE THIS HELPS!!!!!!!!!
