Customer Question

1991 cavalier randomly starts and when it does as soon as I hit the gas it stalls. 41 pounds of pressure at the fuel rails. I unplugged the ony injector I could get with out pulling the intake and put my noid tester to check power to that injector and the car started with a skip but I could give it gas on problems. I plug the injector in and it stalls and will not start. Unplug the injector and it starts. I have a knock sensor circuit code. What could it be.

Hi, my name is ***** ***** check the pressure with it running, and watched it to see if it drops below 41 psi, when you give it gas?
