Read the section of the manual on the idle circuit, it may help some. Mine is still pig rich at idle, but it doesn't foul plugs.

I am told that there is only one cam avail from Nissan, and as they know how to play the game, it is superseeded sp? to allow the 240, 260, 280's to use it. You might want to check it out.

I am having a heck of a time getting time to work on mine. I'll be spending this weekend in a maximum security prison, Alexander Correctional Institute in Taylorsville NC this weekend as part of a Kairos prison ministries team. Next week I am hosting a training class at work with folks from here and Europe, and then traveling to England in three weeks for a meeting. Still trying to hit VIR in Oct. but since I had more time I now have delrin outer lower control arm bushings in the back and a tubular swaybar, well almost a swaybar. The arms aren't done yet. If I would just leave this beast alone I would be fine!!!
