nology sparkplugs in a 3.2
 

Hi, Has anyone tried the Nology Silver Plugs, I have an 88 3.2 rebuilt with 9,000 miles on it. Backdated SSI,964 cams,steve wong chip,new speed sensor ,new injectors,new dist cap and clewitt wires, cone air filter,new dme relay, and I still get the 5200 RPM STUMBLE. Any input would be most appreciated .Thank You .. Joe... Im trying to find a great plug and a gap for this situation.Its got to be something simple... P.S . does anyone know which part of the D.M.E to observe under a magnafying glass most prone to a solder crack...Thanks again Joe...
