"Hi I'm Doug. I work with twenty great guys in St. Louis at Doug Jenkins Custom Hot Rods, and we're going to do some work for you today on Expert Village. Okay, now we're going to install the left side exhaust manifold. He's got the studs driven in there. This is the 02 sensor. He'll go ahead and install that in the bung that's in the manifold there. That 02 sensor reads the quality of the exhaust and sends a signal to the computer to adjust the fuel air ratio, the mixture there, and without that the engine won't run correctly. So this is much the same as the right side. It looks like it'll go in without horrible modifications and cutting. Same sort of careful, straight forward work."
