Haha I'm anything but an enviromental wacko, haha. I normally would weld in a test pipe but the car is a 1998, and has OBDII, and since it has a sensor AFTER the cat I dont want the computer to throw a code. I allready ordered the cat and will install it next weekend. Today was weird though, it did not misfire at all, but it seemed sluggish. Then after backing up a concrete step into my garage, and installed some new light bulbs, I turned the car back on to pull it out it was misfiring. Weird, I'll just replace the cat.
For the temperature thing, I'll have to find someone with an infared thermometer and I will check it out.
Thanks
