Thanks...I will give it a try. Cheaper than a dealer visit. I bought the tech manuals and parts manual on e-bay for about $40 so together I hope to save money and get my old motorhead juices flowing again.

Quick question....can you reset the SES light and the Oil Service Light with the Actron cp9135?

If you go to a local car parts store, most will hook up a obd2 for free. My local Autozone does it for free.

Your O2 sensors have heaters in them and it looks like one of the heaters has failed -- I would check the connectors to your oxygen sensors and if they are ok then you probably need to change out your after cat O2 sensor.
