Well, yesterday my vafc shut down on me for a few minutes... Not to sure why, but on occasion it has done this.. Then, get a CEL cause of presure sensor being MIA and the whole nine there.. So, i shut her down and fiddled with it until the Vafc came back on.. Now, I have a msd Ignition and coil.. Usually there is a very faint clicking associated with it.. Today when I took off the clicking was identical to the msd sound, yet 10x as loud... Noticably loud.. Definently throttle related and my redline dropped to 6500 today.. I guess I should reset my ECU to see if it goes back to the stock h22 redline... But that wasnt a major concern to me.. Anyone have any ideas to whats going on? Im hoping I didnt burn a valve or something... Its seems fine, but its a loud throttle responsive clicking.. Not a bad clicking sound, as in something torn up.. But Im kinda mad right now... So, tell me what you think is going on... And, I am sure its in the engine bay, but havent had time to locate anything better...

Well, my egr blockoff made of aluminum flashing was the culprit.. one of the nuts came frre and popped off.. So, under acceleration it would click or as I like to say clink clink..
