tj are you still running the stock L36 fuel pump whit the cold air maybe its running very lean that plug look like it melted

Yup stock L36 pump but when we checked fuel pressure it was up to par. But it was warm, so it is worth checking again.

TJ, side-gapping is a spark plug modification, not a technique for gapping. Google it.

ahhh, i see. Thanx

i would think that engine running lean because whit the cold air last time at the track youre time where way off youre PB of 14,77 i think

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 :(

Running rich on one or two might make your single O2 sensor to lean out all the cylinders, causing a problem on one or two.

Let'* see all the plugs.

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.

There never was a resolution posted, and appears to be an isolated incident. Might be worth checking, however.

Umm, i really dont know how to answer that. I would say from the threads down is covered in carbon.


None of the porcelian was cracked on his plugs, but recently i cracked 2 plugs on my bonneville, same plugs, also bought from the same place. Maybe that is an issue.
