so i just wired up the knock sensor up today in my obd2 gsr hatch when it was hooked up my car ran like **** but when i disconnected it from the ecu it ran good i just think i didnt have a good connection but i just want 2 take it 2 my buddy shop will it be alright 2 drive my car without the knock sensor hooked up and wat does the knock sensor do

 

Its not good to drive without a knock sensor installed. Are you sure you have it wired up right? A knock sensor does exactly what it says, it detect knocks within the block and adjusts the ignition timing if necessary.

 

my buddy shop is like a mile in a half away if i take it easy i wouldnt be damanage anything would i

 

knock sensor detects any knocks.. if your car has any pre detonations.. it could be harmful.. i doubt anything will happen on a mile and a half trip.. but you never know.. push it there.. heh .. or flat tow it if its that close..

 

a buddy of mine did a swap from ls to gsr and never installed knock sensor and drives it evryday without it and has no problems so i doubt u will have any problems driving a mile
