Thanks to your advice I purchased Car Diagnostic Pro and an OBDII Bluetooth. So I was able to adjust the CMP
correctly it is 0.1°.
I've tested:
-spark plugs(AcDelco and news)
-Sparks OK
-Rotor and Delphi distributor cap OK.
-new coil.
-taylor spark plug wires 8mm OK
-new fuel pump
The misfires concern cylinder no. 5 and the spark plug is slightly damp.I feel that the engine is running poorly
Where are we on that knock sensor code? You have confirmed the 5v bias voltage at the sensor connector from the PCM? Here are some ideas on testing the sensor:

Hello,
first of all thank you for your video links.
I tested the voltage of the wire coming from the PCM and I got around 5V yes.
The sensor itself and its socket were replaced by the previous owner and are new.
So maybe it is not tightened to the specifications (19Nm I read somewhere on the forum).
I need to get a small dynamo to check this.
Hi everyone, I finally solved my misfire problem so I'm sharing the solution to help those who need it.
after changing the injection spider without success, I finally noticed that a wire was cut at the injector socket. this wire was the ground of my injector number 5. thanks to you George and those who helped me.
