This is my first post in any thread help site, please inform me of any mistakes/procedures.

I got a 2001 GH-NM35 Stagea with a VQ25DET engine, very cheap and driveable because of a blown noisy turbo and check engine light causing limpmode it seems.

A few days after buying the car and getting a stock replacement Garrett turbo, and having it installed at my local shop, I was told the car had codes "P1110 & P1135 Intake valve timing control banks 1 & 2" The car mostly drives in higher gears, doesn't agree to rev over 2-3k rpm, I noticed some misfiring and slightly rough idling; and on another note I'm unsure if the loud jet-like spooling sound is normal.

This is the first car I own that is forced induction, and isn't a 90's sports car, I'm 20 yrs old and the same mechanic shop said I'd need to do my engine timing to clear the codes and fix the car's limp-mode. With a oem kit+labour this would be well over $2000 AUD. I would normally and confirming do any repairs to my cars as I'm used to simpler builds. Before I proceed with it I'd like some advice in doing some troubleshooting on my own as well as anyone's repairs/knowledge regarding these codes and symptoms.

    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
