I recently purchased a 2001 Jeep Cherokee that my son found and had to have. I knew it had an exhaust leak that I thought I could fix or get fixed fairly easily. However, after searching deeper into the problem, I found that the engine had been replaced with and older model, I believe to be around 91-95 based on the casting numbers of 53008405. The 2001 Jeep Cherokee has a two piece manifold with two C02 sensors. Two more C02 sensors located in the two cat converters, just below the manifolds. 91-99 4.0L engines had a one piece manifold with no C02 sensors. With that foundation laid, I have a 2 part question. Obviously, the 2001 two piece manifold will not fit the 95 engine because exhaust leaks from the bottom side of the manifold. It doesn't completely cover the exhaust port. If I install the 95 exhaust manifold, and cut out the two cat converters, what do I do about the 4 C02 sensors? Anyone else run across this problem before? Thanks in advance for any help you can give.
