so i put the car together again today and with new spark plugs and the noise was still there but it faded away on idle completly for ages until i drove the car a bit nd then it came back 😅 i plugged my diagnostics in and lookd at live data at 2000 ish rpm my spark advace from ecu is bouncing all over the place?? only seems too do it there though so i poked around and found a cracked colloapsed vacuum pipe that is a t shap in the middle of the intake manifold, could this be caysing my noise and timing advace from knock due to unmetered air in cyc 1 that said ive no maf lol
