Thank you to the tech who answered my previous question...I have another related to the first question.

Since I'm on a tight budget I looked online for a new exhaust manifold. One was 43 bucks..basic. Another was 85 bucks with an oxygen sensor in the manifold. I also found one that comes with the new studs/bolts and a new gasket for 119 bucks, but doesn't say whether it has the sensor. What would you buy....or am I over analizing this whole process?

You are over analyzing :) .

NAPA and Advance both sell them. There should not be an O2 sensor in the exhaust manifold (on U.S. made cars), it is in the exhaust pipe so make sure you get the correct manifold. I believe they come with bolts and gasket.
You want an exhaust manifold for (U.S made) a 4AFE, VIN code "6" (the eight digit of the VIN).

If the O2 sensor has more than 60K on it, I would change it also. The O2 sensor is pretty cheap, since it is a one wire unheated sensor.
