Also, unless you have pulled the plugs out whlie the car was hot under load, Rich and Jake have both advised me the reading plugs is useless. You are just reading them at idle, not under load.
From MD going north up 83, hitt the ramp to the rest stop just before exit 4, and shut down the motor and coast up the ramp to stop. That way you won't have ANY idle messing thing up when you pull the plugs to read them. That said, 1, 2, 4 look rich to me. Zach |

You are just reading them at idle, not under load. (IMG:style_emoticons/default/agree.gif) Back in my dirt bike racing days, we would cut the ignition (panic button) under full throttle, then stop and check the plugs. Anything other than load won't give you any good plug readings ... (IMG:style_emoticons/default/shades.gif) Andy |
