sparkplug diagnosis help

[Stang_ROTY]

OK...that explains way the plug procelain is black, loads up and stoplights, and almost burns out my eyes while I run her in the garage. But I guess rich is better than lean (Mr. Optomistic speaking here)

Two more general question (I know...I never stop).



1) When I'm having starting problems I notice that my oil pressure is present while cranking. Can I damage bearings if I have 20-30 psi oil pressure while cranking for only 3-4 sec's?

2) When trying to hear for "pinging", is it a fairly obvious noise? Do I have to be in the car driving hard to hear it or can I get her to ping in the garage by going WOT under the hood? Basically, can pinging be subtle or is it always the obnoxious marble-in-the-clyinder type noise that I've heard in the past (just not on my car)

Thanks again for the lessons Chris.....you DA MAN!
