Help- Rough Idle, power lost/shift delay

[NoCoScarlett46]

I'm Kate, I live in Northern Colorado and I am in a little deep with my Jeep.

Please help.


I have a 2000, 4.0 and it's given me nothing but problems lately. Just got a engine replacement done and the guy that did it for me did one of the worst swaps ever. Took it back 3 times(just one of the stupid decisions I made) for stuff I found wrong with it and they still didn't put the torque converter in right. After a shaky ride back from Utah, I am now a transmission deep as well.


The newer engine has 95,000 miles on it, the transmission has about 112,000. So I just got it back from the shop(different from the engine shop) and I notice I have a rough idle. Then she decides to slowly lose power, RPMs not reflecting the gas, just not moving past an idle crawl after I try to accelerate from a stop. I ran it 90 miles before this point in the trip so she was warmed up.I get it to the side turn it on and off had to hit the gas a little to get her going.


Next day I read up on common problems and see the IAC/ throttle carbon build up being a problem. So I cleaned up the throttle body and ran Seafoam. I'm driving it around it seems to be doing ok, shifting nice not slowing, except for tonight.


I went to go to work and it wouldn't start until i pushed the gas a little, then ran it to work seemed to lose power/little shift delay periodically. After work started it up and it gave me shift delay into drive.


Any thoughts?


I love my Jeep and I'm not willing to give up even though that may have screwed me over, I can't think of any vehicle I want more(in my price range of course). Not to mention, I've put too much money into it to give up now. Since I'm hopefully done with the huge (hard to do by myself) stuff, I want to do this on my own. I'm sick of giving other people money to make a bigger mess of my xj. I also can't keep harassing my boyfriend for help or he's going to end up burning it when I'm not looking.


I have a realllllyyy basic knowledge of this stuff so go easy on my wording in this, I'm in the learning process still. I'll be really appreciative of any advice.
