Yea in 03 the hemi well at least on my truck anyway only has 2 sensors one before and one after the cat...and there is no EGR valve in my truck either they didnt have them on the hemi's in this year for some reason...I looked for hours cause I thought that could be my problem with the bucking and then did a search online only to find there is no EGR valve...I'm going to get a mopar sensor tomorrow and see if that fixes it fingers crossed

Just wanted to post incase anyone else is having this same problem. I ended up switching out the Bosch O2 sensor and put the Mopar sensor in this morning, cleared the code and took it for about a 10 mile drive to see if anything would happen. It was driving great and havent had the CEL come back on yet so still keeping my fingers crossed but so far so good.

Default Bad bosh 02 sensors.

I know this post is old but if any one is still having problem with check engine light because of 02 senirs or low cat efficacy it's because you can not use bosh 02 sensors they have to be oem I fought this battle for two years now and finally fixed it after spending 1200 on new cats that didn't fix the problem all it was is bad bosh o2
