2000 S TYPE 4.0 with 131K miles
Tbl with DTC's P0420 & P0430 ''Catalyst Efficiency problem on banks 1 & 2''
The down stream (Post) oxygen sensor sends feedback data to the ECU on how the Catalytic
converters are performing.
Root cause - Both CAT's were bad.
The one on the passenger side (Bank 1) was only 4 Months old,and the drivers side was original.
Note: All four oxygen sensors were replaced,because of Age and mileage.
See AF->Jaguar->S TYPE->Misfiring
I replaced two bad CAT's with Dec's from Catalytic coverter warehouse for $500 + $100 for the
install @ Local muffler shop.:smokin:

JAG service would of been a least $3K + All of parts & service to pin point the problem to the Root cause.:evillol:
I designed the ACME AUTO Emissions Filter (AAEF)to fit on my Jaguar, so my emission parts dont' get contaminated with emission gunk.
