Problem After L67 swap (tell me your opinion)
Take off the two screws and pull it out. It'* a $5 valve that sits under a spring. Wiggle and pull it out and pop in a new one.
It'* such a simple device....not sure why it'* vibrating. Maybe it'* caused by another problem. :?

Ok will do tomorrow. I dont know if it is that or not but might as well check it.
I mean i personally think it is coming from the fuel rail. But the pvc is right under it so it may be it.

Well this was got because of a small interior fire.....
I am not sure how he checks them but i sent him an email already with this link to get his input. He is a stand up guy so i have no worries... my brother on the other hand is a little worried. But i am not the one that forked over the money.

I'd hazard a guess that'* about the speed of an injector. Does it appear as one cylinder is misfiring or not getting fuel?
One way to test which cylinder is acting up would be to pull the plug wires one by one and see if there'* a change when each is pulled and reconnected

It sounds like either a bad pcv or a vaccuum related issue of some sort.
we have installed alot of gen 5'* and heard similair noises until we installed a breather due to PCV system not working. Sounds like a box of rocks, similair to this noise.
I would run the car with the oil fill cap off, noise will be gone is my guess.
Either way, I wouldnt panic, sounds like a small issue a little troubleshooting will find. check fuel pressure, vac at idle, remove */c belt etc...
calling you now.
