only thing i can think of from that gargling sound is maybe the exhaust studs are backing out of the head, happened to me, driftmotion.com has a good kit for it and if ur patient enough and have a strong hand u can do it without removing the head:bigthumb:, try to locate the sound if its under the hood or just from the exhaust and let us know what u find.

Alright I found the problem i was changing the spark plugs and came across the 3rd spark plug wire and it was torn in half so I was missing a cylinder but thanks for all your help.
