mine seem to make a strange noise ? not very loud but can just hear a sort of humming noise only at idle ?
yeah something i didnt think of fuel pump is now hot wired so now has 14v at idle instead of 9v so i guess is pumping and returning lots of fuel at idle now.You serious mate?
You shouldn´t hear your AFM at all. If you do, you need to go to the doctors. :rofl:
Seriously, you sure you not hearing your aftermarket fuel pump? This is common.
