hi there,
so I am new on this site and have joined in the hopes that someone will be able to help me with the issues I continue to have with my 2006 XJ SV8 since doing changes to the engine, exhaust, and remapping of ECM.
So to date I have added a K&N air filter, a 1.5 times pulley to the supercharger, have deleted cats and added bungs as per paramount, then I have had them write me a program for the car also. The exhaust is quicksilver performance and has been noted to paramount when requesting the remapping work.
I have since also changed the transmission fluid, filter and electrical plug sleeve, then changed all 4 O2 sensors at once which is when the issues really began to appear.
I have attached a photo of the codes I continue to get continually....any help would be great!
Thanks

 

Seems to me that if you delete cats you may have all sorts of codes triggered by the exhaust sensors.
But specialists will better help you

 

The changes and software are incompatible, clearly. I suppose you gt tweaked software or revert some changes.
