I know that recommended spark plugs were mentioned in a recent post but I can't find it. So, again, what plugs do you guys recommend for my 91L? She currently sports a set of AC Delco R42XLS plugs, installed by the Alfa mechanic who refurbished the heads about 25K ago. One of these is fouled, resulting in an uneven idle (a simple cleaning gave me back a smooth idle -- which lasted about 2 miles). In times past I used NGK plugs but I've forgotten which ones. I recently noted that Steve recommends Champions (the post I can't find) and there too I don't remember which ones.
Of course, I need to figure out why that particular plug fouled and not the others. Maybe a bad spark plug wire (the wires are original and there's 115,000 miles on the clock)? Perhaps a faulty connection at the injector, or a dirty injector?
I appreciate your two cents worth and favorite plug recommendations.
