ok so my jeep is a 1993 jeep cherokee stock except for a 8.25 rear axle. idk if that changes anything.
here is the problem when i start my jeep up in the morning it starts like a jeep.. but when i go to pull down my drive way my jeep wants to rev. all the way up to 4.5k rpm when im acellerating for 0 to about 35 or 40. with out down shifting. and i found the best way is to take my foot off the gas and wate 2 seconds them acellerate again and it stops. its not a major problem just want to know the cause. so i can spend money on an up grade lol. no but serouisly the first time it did that and it wouldnt down shift and i was going about 50 with 4k rpm. going highway not foot to the floor. and normaly rpm for 50 on the highway is like a steady 2k rpm. help plz wana know the cause.....once she warms up she is ok. maybe my girl is tepremental

Try cleaning your tb with seafoam along with tps and iac

I had the same problem. Mine turned out to be a gummed up EGR valve. I had a spare that I cleaned before installing but, you can clean yours up and see if that helps.
