Hey, i installed my header about a month ago and lately the idle is kinda rough. i did not change the o2 sensor at the time, but it did look kinda bad. ive read some old posts and i think it has to be the o2 sensor now. does anyone have the PN for the Delco sensor?? btw, its a 97 2.2 cav
Why just parts at it? A shop could easily tell you if it bad, the cross count will be low. Plus your check engine light will be on.

I'd try running some dry gas in it first, may be some water in the tank seeing as were in winter now.
I'd also check the spark plugs.
an 02 sensor would throw a code or give you horendous gas mileage.

Check for codes like Rob said. Good luck.
i bought some Delco plugs over the weekend. trying to find a nice day to put them in. hopefully that will work. my friend so i guess ill pass by his house to check if i have any codes that arent showing up.
