Thanks I was changing my Valve cover gaskets after 240K so I thought to change everything else like knock sensors, knock sensor wire, water by-pass hose plugs, and coils I did not have any codes but did notice the engine idle go up once three weeks or so ago. i thought it was hesitating also but had it so long and think that any noise is a problem I buttoned every thing back up now I have a code 0325 bank 1 knock sensor any advice and how long can I drive be changing I won't get to the issue of for three weeks does anybody know the cause and effect if I wait and could it be a fuel problem or throttle body position sensor
