I did a complete tuneup on my '84 Cutlass over the weekend (N/A 3.8L 2bbl) and noticed that the plugs that were in the motor are not what was called for.
It had AC Delvo R44TS8, I replaced them with the recommended R45TSX. I'm not real sure what the number mean, anyone care to enlighten me? I know my Camaro uses R43TS. The electrodes on the plugs that came out were white.
The car runs a ton better, but I don't think the sparkplugs had as much do with that as the fact that everything was worn out.
