I swapped the rear 02 sensors from side to side. Erased P2098 code drove to 5 miles to I65. CEL came on shortly after reaching 70 mph. Checked code and it had p2096 and p2098. Plus another that said low voltage on 02. So I ordered two new sensors from E-bay for $22 each. They said it would fit but I found that I had change the four wire connector from my old ones. No problem 1 black ,1 gray, 2 white. Same test drive again light came on at highway speed.
Cleaned MAF sensor(CRC MAF cleaner) Cleaned throttle body(brake cleaner). Replaced TB gasket. (Felpro part number 61594, $3.99 from NAPA.) Test drive all clear. All an all very easy job. The small town dealer I bought it from had tried to clear the light with no luck . Thanks to all the help on this site. I will report if it comes back….

 

try swapping the harness connectors
the long one goes to the closer sensor

 

The code did come back. After a couple shops found nothing. I took ito a MB shop. After they replaced $780 of parts. They said I had a bad Cat.. I took it to the dealer he keep two weeks then replaced the Cat. No charge . It has been good for 2 months.
