well my msp is fuel cuttin in second thru fifth gear, it does it when the rpm's get around 3k with the throttle pressed a little harder then granny drive style. i can also hear the turbo spool up, it pretty loud. and when i let off the gas it sounds like i have a ssqv blow off valve! the motor also has a vlve tap noise at idle that is louder then normal!! i am just lookin for the best answer to fix all this. and also if you guys think that i might still have warranty on the car? i also have a video of the valve noise!
fuel cut, check engine light with a loud valve tap!!

Im having the same issue man, check the cylinder head cover bolts, mine were loose.
Also sounds like a boost leak which im still trying to find mine aswell.
Valve tap, this engine has noisy lifters but check your oil
Im used to putting 3.5 quart in the car and now i put like 3.9 and it goes away.(hand)
Anyone else please help this is my problem right now too.
And I have done WGA and everything else.
I read the entire forums over and over lol.
Can we get some new answers to a new problem..
(man I love the way he described this its perfect. I didn't post cause I didn't know how to say it)

well i went to andvance auto and had a quick diagnosis for the check engine light. the thing popped up a p0102 and a p0171. it also said one was for the MAF and other was o2 sensor. it said the motor was running lean??? i unplugged the MAF while engine was running and the engine idled like s*** so i would think that means that its still working?
do you guys think the o2 sensor and MAF can cause fuel cut, and or ssqv blow off noise without a ssqv blow off valve installed?

Usually the pipe cracks or breaks off at the base. maybe the BPV slide off the nipple. Hard to say but it's a thought of what it might be. Look around see if that's loose or anything around there, maybe the vac source to the BPV. I'm just throwing out ideas here for you.
well the CEL turned off and has not showed back up! i think I am the reason the CEL came on because i unplugged the MAF connection! ooops!
well as far as i can feel around without takin things apart i cant see or feel any cracks or holes in any vacuum lines or tubes.
how big of a hole could cause a differance in boost?
i was also thinkin that if there is a leak in the turbo tubes some where could that cause a loud whistle and a ssqv blow off noise when lettin off the gas?

Im pretty sure mine is a boost leak too man, i made a boost leak detector but havent gotten around to trying it yet.
2.5 silicone coupler cap the end and put a tired stem in it make sure its all sealed real tight, then put it on the intake side of turbo and put like 15lbs pressure into the system and listen for leaks.

Does the exhaust mani. have a crack in it?
Any part of the charge system, the WGA, the intake after the MAF, the recircuation turbe from the BPV.

how much boost is the car pushing?
well i think my problem could be either the WGA or the BPV. i as thinkin of replacing both. i want to know if the forge alloy adjustable WGA and the forge motorsports BOV kit are good products?
And with the forge motorsports BOV kit would that take the place of the BPV?

Just get the ATP one for the MSP, it's already set and most people get 7psi with it.
If there is a leak in the charge pipes the ecu will read that there is extra air coming in but the engine will not see it. This can easily max out the injectors and cause fuel cut.

let me tell you what I have gone thru...I have a little exhaust leak and that sometimes throws an lean CEL. Also I think most of us by now are going thru bad maf sensors. Its been a long time since we have had our cars...some of us are running more than stock boost and also running free flowing air filters and that might have messed up some Maf. I suggest you clean with electronic cleaner, dont rub it with a qtip, dont blow on it either...what normally happens is a small film (that sometimes cant be seen) will throw a difference load on the ecu. I went thru it and was getting fuel cut at half throttle and at 8 psi. So that is something to try.
