I have installed new plugs Bosch (12 at 7 dollars a piece)
I have installed new upstream and downstream O2 sensors OEM Bosch
New OEM MAF (thought K&N oil messed it up I had light spay on them)
Put new OEM air filters and took K&Ns out
New OEM Fuel Filter
New exhaust flanges and donuts

2004 with 61K completely stock
Cleaned injectors
Did vacuum leak test
Fuel delivery pressure at about 49-52 psi

On OBD II with MIL on everything ready
'Evap
Cat
Misfire
Fuel
O2s
H02s
EGR

Took to Mercedes guy and he is scratching his head.

What is most odd is I clear codes run car down freeway 80 miles no MIL
Stop to to off tank ant Chevron and MIL comes on half way back home....throws three codes mentioned in subject line

Smog guy puts sniffer in pipes and says all OK but cant pass because of MIL

The P2099 code (and P2096) showed up after Chrysler put warranty tranny in car two years ago

any ideas??
