Isn't cylinder 4 known to run a little lean and a little hotter than the others??

Have you pulled those plugs to compare coloration?

One will be about 1200F, the other about 1350F. Does anyone else have probes just outside of #1 and #4? Are you too seeing numbers like this? What's weird is that before I changed the plugs and wires, the readings were within 25F of each other (basically within a needle width or my optical margin of error). I've only been doing Lambda tuning and haven't started to play with the ignition values (just made sure that they are the 1.6 defaults as listed on FlyinMiata). Insightful comments appreciated. ;-) Mark _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
