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????

 

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.

 

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