When it gets above 80 degrees outside and I have been driving for about 4 hours on country roads then come into town and slow down my jeep's idle is rough and when I try to step on gas it seems like it's not getting enough. It bogs down and doesn't want to go. I put it into Neutral and rev engine and then it goes again but still idles rough and wants to die. Jeep drives fine when cold outside. Just had oxygen censor changed but that didn't help.
