95 yj Inline 6 4.0 stuttering when warm
My Jeep will stutter when it gets warm (revs down then up) while driving or idling. It doesn’t happen all of the time but the other day it did it and it died on me. I got it started and got it home, but not sure what it is. I bought a o2 sensor but found out when I looked under there that when the previous owner changed the exhaust out It looks like they didn’t put a O2 sensor anywhere or at least not where it went.
