sparkplug diagnosis help
I have recently installed a JMS chip and my plugs look very weird. I don't have an e-pic of the plug but the electrode looks like it's silver and it's just bare metal (shiny, rainbow-like color). The best way I can describe the electrode's color is like that of the T2 terminator (the liquid metal guy). Funny thing is that I thought for the first time that I heard a backfire at WOT, which isn't good.
Does this mean I'm lean and I should bump up the fuel pressure?
This car starts really hard too....always taking 3 turns to fire (when cold only). Doesn't timing affect the starting of the car?
