******* hell bud!!!!! I am sorry
I seem to have done a Murray Walker and cursed it!
Apologies bud!
You sure it is not the purge valve clacking up and down like a *******??? Unplug it and see if it stops.........hopefully the noise will cease and you find it is one hell of a noisey purge valve same as mine. My car sounds very noisey and that is with a brand new plenum......all because of the purge valve.
