Is there a cheaper place to get the knock sensors or is there a way to bypass them?

 

Don't bypass them unless you want to risk the engine.

 

I have looked everywhere for a good deal on them and cant find one. Even trying to find ones that go to another car that will work and are cheaper

 

Unfortunately, modern Jags may become very inexpensive when they age, but that doesn't mean that they are cheap to maintain. What country are you in and have you checked ebay for used ones?

 

Im in usa and i have looked everywhere

 

Work the search function and/or Google. There are alternates that are cheaper (memory, suspect at best, says Jag X-Type) mentioned in threads. X-Types had a longer lead, an easy fix.

RockAuto has them for under a hundred dollars each.

Look in EXHAUST and EMMISION section of 2000MY XJ8.
