Lately i've been having some trouble with my 1996 Jeep cherokee. The check engine light came on recently with code 51 (Oxygen sensor stuck at lean position (this may be tripped by a bad MAP sensor system causing a rich condition. If you get hot rough idle and stalling, especially on deceleration, accompanied by flooded engine and difficulty restarting, that can be a bad MAP sensor causing the O2 sensor to try to compensate. If you get poor cold driveability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor)

It sounds basically like im out of gas when stopping at a stop light, and sitting at idle for a while, almost like the car is stalling out. also noticed today that the exhaust is making an odd noise which im guessing is a result of the check engine light.. just trying to narrow down what needs to be replaced.

I linked a video of the exhaust noise hopefully you guys can hear it.

Any help would be greatly appreciated. Just don't wanna spend a bunch of money on different things that may help the problem if i can just go straight to the source of the problem. Thanks!

I'm gonna go out on a limb here and say check the map sensor circuit.

Is there room for two on that limb?
