low idle and surge

I have a 2000 xj with a 4.0 and when I start it it drives fine once it gets warmed up while driving it surges pretty bad and sometimes it stalls I changed the tps , the IAC and the crank sensor already idk where to turn next

Well...I didn't want to bring it up, but mine did just that and it WAS the, (it's) 02 sensor. Yours is a different system than my 90. In this somewhat rambling thread here it mentions that my idle evened out with the new sensor.

"The idle seems even now. Was cycling every 30 seconds. Rpm & Vacuum would drop, then a little surge, even out, repeat."
