Chevrolet: engines, oxygen sensor, fuel pressure

Question
Hello Keith,
Thank you for getting back to me on my question that I asked you. I have another,I tore the muffler off of the 92 corsica that I am using for a derby, Would that make the car run sluggish, is their any sensor on the muffler?  

Answer
Hi Jason, there is no sensor in the muffler, the oxygen sensor is in the exhaust manifold this is how the computer measures the exhaust, make sure you have enough fuel pressure. You need at least 35 psi. I hope this helps you if you need more info just let me know. Regards, Keith.
