Stalling 16 valves

Well, I finally got it, I have had a stalling problem that got increasingly worse as time went on. When coming to a stop, when the clutch was pushed in, the engine stalled. It was very odd, because it was so random. It was the O2 sensor. Simple fix. I also found a cheap version to use for a replacement. 89 Ford Mustang lx 2.3 O2 sensor is the same as the 3 wire vw. Same # and everything up to the last 3 digits (application digits) Works just as well as the universal, 60 bucks, and the vw oem, 138 bucks, and best of all, it's only $39 at Autozone. Just chop the plug and solder it in. Well, Thanks for the help guys:)
