i start up my cherokee and let it run for 2 mins and it bogs out when i give it gas sometimes it will start off at 1000 rpm then drop down to 400 rpm and when i give it gas it will seem to stall out i put it in reverse and give it alil gas n it boggs out stalls should i replace my tps some times when id give it gas it would bogg out then stall id start it and it would be reved up to 2000 rpm and will stay there for awhile ill have to shut it off n restart my jeep i sprayed where the tb was supposedly n my car would bogg out then die id start it then it would kick down idle from 2000rpm almost right off with the pb50 blaster sprayed in before i sprayed it would bogg out then rev up TO 2000 then stay for like 10 mins

try cleaning your IAC real good first.

4wheeldrivenewbie

well where is that located and how do i clean it id like to try that n see what happens i mean i dont wanna go down the rd and stall it then have it race up when i start it would hit something

mike albo

its on the front of your throttle body,its round and has 3 wires going into it.Its held on with 2 screws

4wheeldrivenewbie

That must be the thing i tryed to take off once one of the bolts snapped was a torx screw i almost thought that was the tps i was gonna try n clean it well. idk if i have to take it off?? because the bolts were frozen it wont be easy if i gotta take it off

i pulled out the iac looked like it had abunch of black stuff on it i sprayed with brake cleaner and cleaned it right up the pointy thing was shiney again put it back together and nothing seemed to happen seems like when i put it in drive n give it gas it boggs right out after i let off the petal and dies sometimes if im lucky it will come back up and not die. When i try n start it after it will race up like before but now it seems to drop back down after a few seconds instead of staying at high idle for 5 mins drops down from 2k almost right off. im still stumped i mean i got a slight leak where the cat connects and pipe bends upward torward the headers but i doubt that would throw off my mixture or cause this problem maybe slightly but its goto be more tps next??? or just replace my iac? i belive my iac is working

dude, Grammar please. They teach that stuff in school so when you write a sentence other ppl can understand what you're trying to say.

4wheeldrivenewbie

well zachs if your gonna be hatefull then u can do it somewhere else because i highly doubt u know everything there are many factors to why a person types a certain way some keyboards are touchy some people have broken keys that donot work some have rubber keyboards some people havent opened a textbook in years your reply wasnt very nice and i doubt u would like it if someone critized you. What is it about my car stalling out and idleing real low that u cant undertand other people had no trouble replying and in a decent manor i might add. To bad because i was hoping ur post had something useful for my truck in it. Does anyone know if there is someway to adjust the idle or is that controlled by the sensor it seems like when my jeep is cold it is idleing at 1000rpm then after 2 mins it drops down real low like 3 or 400 rpms and stays there bouncing ived replaced vaccum lines i dont hear any air coming out any of them fuel filter new oil plugs cap wires air fiter???

I'm not being hateful, I'm saying use proper grammar so we can better understand what you're trying to say. Broken keys or not, you can still use correct(or at least something close enough) grammar instead of a 30 word run-on sentence. It makes it very difficult to understand what you're trying to say when you don't.

4wheeldrivenewbie

im sorry man like i said before thought the computer im using has a crappy key board sometimes u press a button and its the key next to it i mean its hard to type and correct key errors and use perfect grammer at times but i think im gonna tackle an exhaust leak in the front then maybe the mixture will correct it self and it will idle better

mike albo

If cleaning tha IAC didn't work your gunna need to replace it then.

ZachsXJ

Listen to mike...he knows his stuff

je4reyk

If your IAC was dirty then I would say it might be time to clean all the sensors and the TB,just a thought!

4wheeldrivenewbie

well how many sensors do i have 4???

ZachsXJ

There's way more than 4 sensors on anything built since 85. You have at least one o2 sensor, IAT, TPS, CPS, MAP IAC...and a bunch more
