You should change the fuel out.

Well I changed my fuel filter today... Didn't help any.. I did find what I believe to be a few vacuum leaks... One is where my perrin inlet connects to the turbo.. Also I think the pcv is leaky

so you think that the leaky inlet tube could be the problem? i just notice that i can hear it pretty good... i thought it was the intake but its seriously almost as loud as the intake... it would make sense also... if it runs better without the maf its because the maf is seeing the metered air and then more air is being added so its messing it all up...and when the maf is unplugged its running off of the map tables and its also throwing codes because of the maf being unplugged and the iat sensor not being read also...

i know there is more than just the inlet leaking , i sprayed cleaner on the pcv valve and it also jumped the idle up..... but if sprayed anywhere near the turbo , where the inlet connects, it jumps up alot more.. i know theres probably more issues but im starting with the inlet... im also gonna pull the intake manifold off and fix the leaky injector and everything.... looks like ive got a task ...
