I got a 2000 outlander xls 112xxx miles, that has started some idling problems at stop lights. Drives fine, the powers still there, but when you stop it starts bouncing around from 800 rpms to 400-500 and wants to die. Checked for codes, said cylinder 4 had misfired. Changed spark plugs and it fixed that issue but it's still idling bad and getting worse. The car is new to me and I haven't changed much on it other then oil+filter and ATF. so I was thinking maybe a clogged fuel filter?

Thought I'd see what opinions you guys had, maybe sensor I don't know about? Or if anyone else has had this issue.

Thanks for the time and any impute.

 

Battery. Check voltage. Lower than 12v, replace.
