I pulled the left bank plugs today. What a PITA. Im not a skinny kid with skinny arms anymore. The plugs I removed are ASF 42C. They may be the originals. Nothing else on this car has been changed. The insulators are bright white. Not tan or brown. No oil present. #5 was a little worn on the electrode Gaps were between 052 and 060. I set the new SP25 gap at 052. It looks to me like a lean condition. I replaced the air filter, cap and rotor, but have not checked the timing or replaced the fuel filter. Compared to a Fox 5.0, the 94 doesn't seem to have near as much power. I have 3.08 gears, but it still seems to be pretty wimpy for a 5.0/5 speed.
