Mine was low before the LWF, and it's low after the LWF, too. Not 500, more like 700, but still shaky at idle without the AC on. With the AC on, it's fine.
My most-trusted mechanic told me that the only real "fix" is to reprogram the DME -- along with the extra benefits of more power, etc. But I'm not sure it's worth the $1400 or whatever.

I had a bit of rough idle and stickiness at about 2,000 rpm. However, I cleaned my ISV last night and now everything is working perfectly with rock stable idle at 800 rpm and smooth decel without any stickiness

I don't know if this is part of the cause but I too have RS clutch, LWF and Steve's chip.

Was wondering if anybody has a reliable way to test the coils. done some searches and there does not seem to be a write up on this.
also need to know what resistance should be on plug wires and plug caps.
thanks..
