well i have had my jeep for a while and I'm looking into lifting it now, i have been looking at the Rough Country 4" Suspension Lift Kit 2001 Jeep Grand Cherokee Laredo WJ any do or don't or better suggestions to whats lift kit should be used.

 

does it stall while your driving

 

It has stalled, but the problem is intermittent.

When it first started stalling I was leaving the city and it died cold.
I started it again and it died again, held my foot on the gas started it again and was able to keep it running.

The next day, it ran fine.

A couple days later it stalled when I got in it to go to work, I got it to started it idled up and down almost like a vacuum leak.

But i can assure you after checking it's not a vacuum leak.

Other day I get in it will run great for a days to a week.

Yesterday I replaced the TPS and cleaned the throttle body and cleaned IAC valve of all carbon.

It was dirty but not as bad as I thought it would be.

 

the cps could be going bad

 

x2

jkiddmk, could you stop yelling please?
Goodluck

 

cam shaft or crank? not sure what CPS stands for

 

Crank shaft position sensor.......

 

thanks for the reply i think the CPS is located close to the bell housing at the back of the block. do you know exactly where it's located?

sounds like thats the next part to be replaced, when it starts acting up again.

i changed the TPS and cleaned IAC valve, and haven't had the issue but i'm waiting being i didn't think that was the issue in the first place but was one of the easier job i have done.

 

I installed a new battery in mine whn it done that and it corrected the problem....

 

Its on the ds on the back of the trans bell house near the top. Pain in the hoohoo to get to .

 

It's easier to get to it from underneath.

 

Your post says nothing about which engine you have.
If by chance you have the 4.7L there is a tsb on the Idle air control valve with an updated version available at the dealer.

 

it's a 4.0

 

well spent a couple of hours replacing the battery cables i had a hard time starting, like the battery was dead. moved the battery cables and it started no problem. i don't know if it was the crappy cables all a long but if its not i will know real soon.

 

CPS will be next
