1999 Jeep Grand Cherokee 6 cyl 160000 miles

How much would it be to repair an engine that isn't running on 6 cylinders. The mechanic called & said that my check engine light came on b/c my Jeep is only running on four cylinders, not 6.

Also, how long would this repair take?
I have my Jeep at the mechanic currently & wanted to see if their estimate to be is accurate.

Cost Depends on what is wrong.

What codes?

I have seen fuel injector issues with this engine that is sometimes cured with a professional fuel injection cleaning.
