Mileage 124,707. I bought this for her 5 years ago with I think about 91,000 on it. As far as I know, they are original sensors. I am thinking a timing issue would trigger other codes, and maybe a P0420 as well, but who knows? When I say stumbles, I mean it jerks fairly hard when giving it the gas to go uphill, etc.

Lost my Veepeak reader while scanning a buddy's car a while back, have another on order from Amazon. Supposed to be here Friday. Then I can get more data.

Had thoughts of just going ahead and ordering O2 sensors, but I don't know yet how many there are on this rig. Looks like the name brands are running over $40 a pop on eBay. Guess I'm lucky they aren't more. Also like to know where they are at so I don't have to remove more things than I have to, just to look for them.

Thanks, I'll post more data when I pull it.
