While I was having my 3L built, I had my mechanic check into O2 simulators to see what prices he could get. He told me that he spoke with a vendor who has dealt with different brand O2 simulators, and passed on some valuable information. This vendor stated that all of the O2 simulators he has sold have a tendency to go out between 3-5 months of use. My guess is this is why Mark has had a Contour Enthusiast Light off and on since he got his 3L back. I ended up using the PC board and resistors listed in the how-to for gutting the precats, and haven't had any problems yet. Of course I have only been driving on this 3L for a week, so time will tell. Just my $.02.
