Hello all, after several test with a software Hand Held Halo on the OBD1 plug from my car, I had 2 errors code. First one is code 22 : engine speed sensor and second is 23 : TDC Sensor. This 2 code looks very different in term of issues on the car and due to the fact that I did the complete timing system, I will try to test the TDC Sensor if by chance it could be the source of problem. As usual, your comments are welcome
