1999 Explorer Sport - Missing Power

[Tim1]

When ever I come up to a hill my explorer slows down to about 35mph every time! A couple people have said it was my catalytic converter. Only other problem is sometimes when I'm stopped it will buck a little bit but not bad.


I borrowed a code reader from a friend and wrote down a snapshot of the Live Data Stream at idle and 2500rpm. I was wondering if anybody could look at it and tell me what they think.
