knock sensor delete?

Hey I was wondering if anyone has done away with their knock sensors on a lq4 6.0. What would be the downside to deleting them (aside from blowing a hole in your piston).

I need to replace mine (corroded) and the connectors (corroded n broken) and the rubber grommets (torn) that seal them. Thought i would save 175 bucks by not doing it.

Re: knock sensor delete?

the purpose of the knock sensor is to retard the timing when it detects knock. remove it and you run a high risk of breaking something or blowing the engine. are you willing to take that risk to save $175?

Re: knock sensor delete?

lq4 might have a "special" knock sensor. im unsure about that. but its still a pretty important part of the ignition system.

wow. Indeed it does.... but agreed. Not worth it to delete. I'd be making a trip to a Junkyard before ordering a new one though....
