engine hissing sound...PLEASE HELP
 

hello,
I just changed my spark plugs, pvc valve, and fuel filter a little while ago and it seemed to run better than when I bought it. When I parked I heard a loud air sound coming from the passenger side of the engine near where the the throttle body, enjectors, and plugs are. Also my fan light came on as well which I have never seen come on. It runs okay but it seems to idle a little rougher than usual. What the hells going on????

pcv items installed correctly? ...does it happen as soon as you shut the engine off?

i just slid the pcv valve right on the same way I always do. Seems to be good. It is extremely loud while the car is running right around the injectors/plugs and it fades out when I shut it off.

well just check your work. especially if it never did that before you put those parts on.

got it man. Thanks for the help......somehow the pcv hose came off!!

yup...no problem. glad you got it fixed.
