Hey Mark, Got my UltraGauge ordered. FYI they have a new model: UltraGauge EM Plus.
For a few bucks more....can't hurt to have a few more bells & whistles (I hope).

Added: Readiness Monitors - Emission Readiness -Gas & Diesel Engines
Added: Performance Measurements - Performance (Experimental) - measures both acceleration and braking performance.

This is all techy stuff which is a challenge for me, but since I apparently need to learn how to fix the car, better learn. Hope the gauge has only "good" codes for me!

Thanks for your help.
