lceah Posted February 1, 2008 Share Posted February 1, 2008 You should post this in the "civic" section... and if your knock sensor is bad, what is happening to you is what would be expected to happen! your timing and air/fuel ratio are not optimum so your car is not fuel efficient... are you going to replace the sensor?

cranny Posted February 2, 2008 Share Posted February 2, 2008 your engine will run fine without t. honda ecu's dont use the knock sensor to make real time ignition changes so ive learned recently when reading about tuning. sounds like you might have a bad O2 snsor. what ecu are you talking about a chipped ecu?
