Suddenly high Knock count

[Osvaldo_colon]

My Rsx Type S with bolt-ons suddenly started to flash the cel non stop under acceleration. I data logged kpro and have no error codes but i see the knock count going up with out any knock. Any suggestions??

It sounds like you may have a bad tank of gas if no other changes have been made to the vehicle. You may have also filled up with 87 instead of 91 octane.

Or something has come loose in the engine bay, or the exhaust is hitting the sub frame.

Tank is half and nothing noticeable is hitting the engine or sub frame, could it be the knock sensor?

[Osvaldo_colon]

It lights cel when giving throttle as soon as i the off the gas pedal it stops

Can you hear any audible knocking? Look in the engine bay for anything loose.

I don’t hear anything abnormal and i have not done any work on the car. It was ok i arrived to work and in the afternoon when i started the car it started doing the flashing of the cel

Have you looked in the engine bay for anything loose?

[Osvaldo_colon]

I did! Everything seams ok

Has this been tuned by a tuner?

[Osvaldo_colon]

I would recommend that you take this to your tune rand have them look at it as you may have a mechanical problem if you are suddenly getting large amounts of knock with no changes.
