I have checked visually for all hoses and clamps securely connected. It starts and drives fine. It has been modded with turbo back exhaust, 007 dv, fmic and unitronics flash and never any issues until the last few weeks when it gets cold at wot then goes limp at 5 psi. now it doesn't pull any boost whatsoever!

I had a buddy rev it in neutral to see if i could hear a leak but all i noticed is the rubber coupler going up to the throttle body near the bumper is moving. I havent ever replaced my n75 valve either.


Here are the codes if anyone can help or shed some lighton the situation that would be great!

replacing both the O2 sensors will get rid of at least 3 codes, maybe even all of them. its running too lean because the O2 sensors are not telling the MAF the right amout of air to fuel.

Should cost you between $150 to $250 for good sensors

 

i have no cat so that is probly picking up an inconsitant reading between first o2 sensor and second.

 

the manifold code is more then likely you MAP sensor that goes into your intercooler. and since neither you MAP or MAF are working, AND your 02 sensors arent working, im absolutely amazed you car even starts

 

if its unitronics tune make sure it was set up to run with no cat. certain test pipes will work and some won't.

 

the second 02 sensor can't make the car run poorly, it will only give you an engine light

 

just for ***** and giggles check the fuse box and the timing fuses, i have a v6 so the codes are probably going to differ but a while back my car through the o2 and maf codes and turns out i somehow blew timing fuse #23, it might be something else but always best to start with the cheapest solution.
