Have a 1997 XJ Sport that is having some stutter and sputter issues at POT. It is worse when it gets warm. Does it worse at about 30% throttle or so... say about 15-45 mph it bucks stumbles stutters and is generally acting like a carb'ed car when it is loading up. It threw an O2 sensor code (High side O2 sensor, Rich condition) the other day but it has since went away. I have replaced the wires, cap, rotor and plugs. I have an idea what I think it might be but I want your opinions.
 
i think its the front 02 senser going bad saying its to ritch making it run leaner so now you are not getting enuf fuel o2 senser downspout look under your jeep you will see it by the firewall
