Hey guys. I just got done swapping the plugs, wires, cap and rotor. I noticed that the plugs were open to about .058". I know that most guys run between .050 and .052. Would that much of a gap (and "burnt" electrodes) cause the car to ping at WOT? The electrodes actually looked really good, except for the excessively worn condition. The ground straps were chalky white. Nice! As a result of the excessive gap on the plugs, the cap and rotor both showed signs of tracing from excessive resistance. I guess 87k miles is too long to go to tune-up a Mustang. (Leave me alone, I "just" got it a year ago.
I haven't had a chance to drive it, yet. I hope this means I can go back to 87 octane gas, for a while. (Just because that means the reason for the ping has been resolved and I can move forward to some upgrades.)
