Just a quick easy question for most of you out there.

My wife's Grand Cherokee (4.0L) needs the O2 sensors to be replaced. The vehicle was originally sold in VT (that's where we bought it from) but it has the CA emissions conforming sticker under the hood.

So do you think I need to replace each O2 sensor with the CA version or the federal version? Does it really matter? I would think that it would affect the fuel injection if I replaced these original O2 sensors with the wrong version.

Thank you in advance,
Matt

Question answered.
In 1999 Jeep went to two sensors upstream and two sensors downstream for CA emission (federal only has one up and one down). Joy, just verified that I do indeed have CA emission :(

Hopefully this will help someone else in the future.
