Spank you very much!
On topic, it'* normal to see a variation from car to car just from the error of the Tach. Use a scantool to see what it really is. When I calibrated my rpm'* on my Gtech, I used the scantool for reference. My Tach varies very little from the scantool, but I've heard of others that vary as much as 300 rpms from true at idle.

Scantools are great. I can actually see the rpm that the PCM is 'requesting' and trying to maintain, as well as the rpm the engine is running at. This can be a big signal when troubleshooting a problem.
