2002 PI Fouling Plugs
My work car (a 2002 Ford Police Interceptor) has a bad habit of growing very sluggish off the line. The PD mechanic changes the spark plugs, and it runs like a new car....for a few weeks, until the new plugs get fouled.
Has anyone else had a problem with a CV/PI fouling plugs? I will admit that I never shut off the car, once I start it at the beginning of a shift it stays on until the end (I lock it up when I'm away from it, I have a second key), so it idles a lot. Could this be a contributing factor?
