Hi, I have a 2002 Acura Rsx 5 Speed Base. I recently had a misfire in cylinder #3 and I changed all of my spark plugs and ignition coils. I also had a Vtec system failure and I changed out the Vtec solenoid. My belt was old and dirty so I changed that as well. The only code I had left was p0325 (knock sensor) I have the piece it’s just I’m not sure how to change it. I was driving and my CEL started flashing signaling a misfire. I went to autozone and got the codes checked and this came up (see image). Does anyone might know what this is? I believe it can possibly be the ECU. I’m only 16 and this is my first project car, I have a daily at home, but this is just annoying and stressful. I had so much plans for this car but these problems keep interfering.
