I just wanna know what the likely performance loss is if u've got a bad knock sensor. Maybe it's just me or the code but i lost 3mph in my 1/4 since this light has come on and i wanna know what kinda power loss i'd suffer from a bad knock sensor

 

It pulls 4 degrees of timing across the board if i remember right.

 

also it drops you to the low octane table... it's hurting performance bad... I had a P0327 a while back... fixed it at the track... I lost over 1 second in my ET from the code being set

 

think i should replace both sensors? or the wiring harness

 

Depends, did you recently have the intake manifold off?

 

yea, did a ls6 swap

 

Chances are you pinched the wire under the manifold and it's grounding out on the block. Either that or you unhooked the wire and forgot to plug it back in after the swap. That's what I did (yeah I know it doesn't have to come off, i was just unhooking everything). Anyway, i'm guessing it's the wire and not the knock sensors.

 

^^^^ ditto... search for posts in this section by me (horist) w/keyword P0327

I pinched the wire when I did my LS6 intake upgrade

 

alright, thank man i appreciate it
