93 Jeep Grand Cherokee failed MD emissions (Nitrogen Oxides) but no check engine light.
Replaced O2 sensor and EGR valve.
Started up fine, Check Engine light came on, drove a mile and when I parked it, engine died..
Engine won't start or run unless I'm on the gas pedal.
Dies when I release the pedal.
Any help will be greatly appreciated!
Thanks

Did you disconnect the negative side of the battery when you changed the sensor? Whenever you change a sensor or make adjustments to a sensor you have to let the computer recalibrate for the new readings. Also, as other people have mentioned on here check the throttle body and cap and rotor. I clean the throttle body on my 96 JGC religiously so I have not experienced this issue. I would suggest starting there first. See if that helps and good luck.
