Hello,
Recently I went to the track and was unable to get any clean runs in because my car wasn't running right most likely due to a bad MAF (car doesn't idle at consistent rpm's). Anyway, on my second run I detonated 19.9 degrees of knock near the top of 2nd gear before I let out running 21 psi on a stock car. Since then when the car is idling I hear a loud ticking or popping noise coming from somewhere near the intake plenum or right below it. I checked and it's not coming from a specific valve cover and the noise is not consistent but it is always there. Sometimes it's once every second sometimes it's every 1.5 or 2 seconds etc.
What could this be? And could my fuel problems be due to a fuel system issue? Does Fuel Pressure rise with RPM or with boost?
