Sporadic Ignition Miss

[Leigh]

I've got a sporadic ignition miss on my 94 MTX that I can't identify. Cleaned oil from wells, didn't help. Got a front Oxygen sensor code. Would that cause a miss?


Supposed to have new plugs/wires. Found this really bad ignition wire connector, but it has low resistance, good spark. What would cause this? Water? Cleaning solvents? Sparking?

As far as I'm able to tell from the image, it looks as if you've had some tracking on this connection (arcing up the side of the plug due to contamination ingress).

But, alas, the image is not that great, or maybe it's my eyes, but it looks a bit blurry to me.
