This thread is meandering all over the place for a solution. Exhaust, air flow, fuel flow, electronics…. I can’t keep up.
Out of interest, have you followed the order of the pinpoint tests in the workshop manual?

 

so I am replacing injectors in the jag.. do I need more than just the seal at the super charger on a 2007. can i reuse the clamps they apear to just be aluminum. and i will of course need a set of manifold gaskets.
Is there anything else i should order beforehand.

 

also just put in new jag coils got better but we decided to try injectors as its still misfiring under heavy acceleration.
