is this normal

[chook69]

ok! evry time i take the car out an back to home again from a drive. when you turn off the engine it makes a hissing noise an it sounds like it cuming from one of the injecters on the driverside of car or its cuming from the manafold intake system! so is this normal. (it sounds like its releasing presher)
tho my mech should pick that hissing noise up! Right?

can i get help on this also pls?

thanks.....

its the fuel going through the pressure regulator for 5 or so seconds after you turn engine off, this is perfectly normal.

is it like a schhh, or like a buzz? both are fine, and the schh is the pistons moving in revers because of the compression and letting air out the intake
