I agree, the car has felt sluggish. Was running low 15'* instead of mid-high 14'*. Trapping only 90-91 instead of 94 it was trapping. So that may be showing something. But all the plugs were dark (i mean black black) and smelled fuel strong. So to me it wouldnt be showing a lean condition but i may be wrong :(
I am going to send the plugs to Bill boost tomorrow. And have him put some pics up. My camera is just not made for the close ups, and all i am going to do is confuse people. I can hear it now...."what is that in those pics, are those actually plugs.... just looks like fuzz)
Any indication of carbon tracking around the insulator? Remembered a thread from last year where "The Engineer" was having problems with Autolite plugs cracking. http://www.bonnevilleclub.com/forum/...ic.php?t=53249
There never was a resolution posted, and appears to be an isolated incident. Might be worth checking, however.
