All i can hear is either an air leak or was that from a cold start and the air valve is open, the other noise is the injector solenoids click but really hard to tell from the sound clip

describe what were looking for

It gives me that two codes, knock problems. I have changed the spark plugs, the cables, fuel filter, rotor and cap distributor,

the temperature coolant sensor, the knock sensor, doesn't have air leaks.and the problem continues. I didn't saw the injectors..Does that noise seems to be injectors problem? thank you very much

yesterday i've clenead the injectors by ultrasonic machine. the problem still continues. not injectors problem.

tell me one thing please, what is the map sensor function? my

situation is: at 40/50 miles p hour the light stays on, don't

disappears. but if push him to 120/130 p hour with high rpm, the light

disappears. in very hot temperatures light disappears more times too,

when very cold she stays on! does the map sensor have anything to do

with it?

i've replaced:

- distributor cap and rotor.

- water temperature sensor.

- the knock sensor.

- spark plugs, and the wires too

- changed the distribution belt and the water pump.

- TPS sensor.

on 5 to 10 sec. in the video its perceptible a noise. can the map sensor, who controls the pressure, make that noise?

i also experience to set off the map sensor, and the car runs equal
