I posted a thread yesterday. The response I got was that I may have a boost leak. I'm not convinced that is the problem. I was cruising along the highway this morning and it was boosting at max 13-14psi. So I got my vgate vscan unit out (similar to actron) and just hit the erase codes button while driving. I got back on the throttle and my boost went up to 20psi. Car is not throwing any codes now. In the past it would give me a pending PO101 code and only boost to about 4psi. Like it goes into a shutdown mode. I've only had the car for. A few weeks....still learning about these things. Any help would be awesome.

 

I made the boost leak tester. I just got done testing, the system seems to be holding pressure just fine and the only place I can hear a tiny tiny bit of air coming from is the hose off of the engine for the PCV valve where I disconnected it from the intake.

 

That check valve is leaking then, replace. How much pressure did u pressurize system to in test?

 

About 20-25psi

 

I looked online at parts stores
....where the hell do you buy a new PCV valve? Dealer only?

 

Possibly create engine depot I think is where I got mine. U get the entire line

 

If the code comes back and u got no leaks, get new maf

 

Got a new MAF still getting the code but I clear it while its in pending because I hate driving the car at less than 5 psi. No boost leak. Can't find the check valve anywhere? Why is it hard to find this part?

 

Cause u have to buy the whole line. I shall check

 

Tube LNV PCV 12598298

 

Don't ask me why it says lnv, typo I'm guessing, but that's it

 

If it don't fit , do what I did and make ur own out of braided stainless line, and take that check valve off that one and put it on ur new one.
