tickin from intake mani

[sleepintalon]

hey guys i've got this annoyin tickin comin from the intake manifold, behind the injectors. i noticed that it might be the mdp sensor but i wasn't sure if it was that itself. it clicks all the time even when i'm just sittin in park and idlin. i can't pinpoint it exactly but thats about as close as i can get. any help or ideas would be appreciated.
thanks for lookin

i also get that ticking noise from the intake manifold, but only during cold start ups. i also cant find the pinpoint of the noise, but after a few minutes of warm up, it goes away, but it is a pretty loud ticking noise.

its probably just the injectors tickin...i wouldnt worry about it...dsms are suppose to make weird noises

besides cleanin is there anythin i can do?? i just don't like other noises that aren't supposed to be there.

could also be the purge valve solenoid ticking. The driver side of the 2 black solenoids on the firewall just above the intake mani. Put your finger on it, to feel the ticking.

i already replaced that. one of the two solenoids on that brackets was goin so i ordered it from the dealership and they sent the whole bracket with both solenoids on so i know its not that.
