As you know we have seen a lot of posts related to Restricted Performance on our forum. Both Brian Schuette and I talked about the many issues that could cause this problem and the different techniques it troubleshooting the problem and how it should be pulled together to help others. Well we are attempting to do that. I set up a Trouble Shooting page http://www.gusglikas.com/AutoRepairTroubleShooting.htm on my page and we will list what we can put together. Brian has a unique way to simplify the procedure and put it in writing. We hope it will help you to identify your problems.
