I am curious as to whether anyone has heard of or used the ok spark plug sensor; here is their web site address www.okspark.com. Please let me know what you think, seems like a pretty handy tool to have around for diagnosing misfires. Thanks Jeff

 

Good god man...Not worth it for $190.

 

They have them on ebay between 130 and 180. The reason I am asking, it would have come in handy today on my 2000 4x4 silverado DD. About 2 days ago, my truck started loping at idle or stopped at a intersection. I replaced the plugs and wires 6 months ago with AC rapids and wires are cranes firewire. Ya, the wires are junk. I should have sent them back when I first got them because I had a hard time getting the wire to snap onto the plug. If it wasn't for the bright spark and ticking noise on two of the wires by the Exh manifold, a tool like that would have come in handy. I tossed the crane wires and replaced them with the MSD set I had on my 2001 silverado, truck runs smooth again. I will just buy another set of MSD wires for my 2001 cruiser.

 

Save your money and just use stock replacement wires.
