2002 jeep liberty. Check engine light is on and engine idled rough and will not stay on. What could be the problem? I replaced the air cleaner filter, spark plugs and the pcv valve. There was no change.
Do you

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

1st thing you need to do, is GET A CODE NUMBER (thats why the engine light is on, its telling you that it has detected a problem)

I do not know your situation, If you can get it to Autozone or Advance Auto, others too, They can code it for FREE!

They can usually tell you what the code is related to, maybe sell you the part and show you where it goes

You can also purchase a "READER" at those stores

My primitive ways used to be, LOAD UP on the Car dolly and drag it down there for the Test, if I was not running

I also sorta got to be a regular, and sometimes when they closed, I could get an employee to drop by and code it at my house

But now I have the Machine (the lower end ones, are really not too expensive (get at the parts store). You "WILL" need it again (trust me), or you could rent it to your buddy to get some reimbursement)

If you do code it at home, the Auto Stores, will still help you with the "CODE MEANINGS" and parts

If not, Resubmit your question here (a new question) with your code results. One of the ASE certified guys will help you determine what to do next.

Regardless, whatever you do, let me know if it was simple and inexpensive---normally its a sensor less than $100, maybe a lot less!
