Gutting of the pre-cats went great. The car runs alot better than it ever did before. The wierd thing is that I no longer have A/C. I had it checked out and the same shop said that there was very little freon gas in the system. It worked fine when I took it in for the cat gut and I notice it not working a couple miles after leaving the shop. Do they have to mess with A/C components while gutting the precats. They are claiming no responsibility for the A/C problem. Maybe it was just a coincidence. Thanks, John. 98 Contour V6 ATX
