Last time I got a bad knock sensor code (Left bad), I swapped the
connectors (L to R and R to L), still got the same code (Left bad.) 
Ended up being a bad ECU, swapped it out with ECU from V8Q #2 and no more
codes, put #1's ECU into #2 and got the bad knock sensor code.  It was
definitely very detrimental to performance and fuel economy, car felt
like it had a new engine, I think the rest of the ECU was defaulting to
pre programmed timing etc. because of the reported bad knock sensor.
