so i heard a rattling acoming from under the hood and noticed that it speeds up with engine rpm... After feeling around with a dowel i found that the rattle was coming from the fuel rail and/or the return/inlet lines in the front of the rail. at idle it sounds like just a random click, but when the rpms go up a little it sounds a little more rhythmic. could this be the Fuel pressure regulator going bad? or something else like a damper??? no idea. thanks

 

Anyone????? possibly an injector???

 

ok nevermind. i', retarded. all fixed up and gained 35 HP in 6 minutes and a wrench.. ;-) don't ask...
