    Knock sensor

    Not even sure why I'm posting this... I know the answer.



    I guess I am posting this to ask one question... is this going to mess up my timing advance? I can deal without a knock sensor for right now... but I'm taking the car to the track this weekend and really don't want my timing to retard. I know I'm not really knocking.

    How much does a used sensor go for? I still need to do some diagnostics before I buy one, but I might as well start inquiring now.

    Vacuum reduction, Powdercoated misc, cruise relocate, Evo9 BOV, Custom catch cans, Russell fuel filter, SS braided fuel lines, High flow fuel loop, Autogage fuel gauge, Catless DP, DNP Y-pipe, Fuel pump hotwire.

    Yes it will mess with the advance. For approximately every 3 counts of knock my logger sees the car pulls 1 degree. This may differ from car to car but it's what I have noticed on my car. Good luck at the track.

    You're right. I'm seeing timing reduce to a mere 2 degrees at WOT now.

    Wow, this sucks. Everything that has NEVER gone wrong with my car is happening this week. ARGGHH.

    Get it fixed. It's simple and relatively easy. Just pull the intake plenum, and then the lower intake manifold, and there it is. You probably know this, but just for reference.

    oh yea... no big deal on replacing the sensor. I feel like I'm down there once a week, lol.

    Problem is that I am going to the track this weekend. It's OK though... I think I found one kind of close to me.

    Still need to do some testing with the meter to make sure it's the sensor.

    I would say 99% chance its the sensor and not wiring. I am just trying to diminish your hopes so that when you find out it is the sensor and not the wiring you won't be so upset.

    lol yea but the wiring check is free since I know my way around a multimeter

    I just picked one up from a local member so it should be installed by the end of this week.

    I'm actually going to the Glen this weekend. I'm not sure if they actually time the laps because it's a road course class... but it's pedal to the metal all day long.

    Oh, and I just found out what my wobbling noise was... bad wheel bearing what a week.
