Question about 1993 Jeep Grand Cherokee
I checked the TPS and MAFS, replaced the O2 sensor. No codes.
Starts and idles fine. I have an exhaust leak in the tube that runs to the EGR valve at the Exhaust manifold . could that leak cause the engine to run bad? What else could it be?

It can cause it to run rich because the oxygen sensor may be getting a false reading as to how much oxygen is there....this in turn causes the pcm to add more fuel
