Cold start bogging...

'89 4.0 aw-4. Started after I replaced the o2 sensor. I start it in the morning and it starts the same as usual but it seems like every 60 seconds it bogs badly and dies if i'm sitting still in park or drive. The problem continues until the Jeep has warmed up to the 160 mark. It also seems sluggish until 3000 rpm when it really takes off. Anyone have any input for me, its kinda annoying.

Im does the same thing exept it doesnt die. i have a 97 so its a 4.0 intercooled and i also have the AW4

Try cleaning the Throttle body with a spray cleaner.
