Just got my car back from mechanic on the corner of my neighborhood. Honestly, never really been impressed with the work they do and the integrity of the workers. However, they are fast and don't charge a whole lot so for some jobs I don't really mind.

However, I just got my car back from them after asking for them to do simple diagnostics, and I was told my car was throwing three codes :

P1615 - NATS Malfunction
P1564 - ASCD Switch Voltage Signal Out of Range
P0113 - Intake Air Temperature Circuit Signal High

I'm still just getting into cars and have had my Z for a bit over a year so I'm not 100% sure what this all means, but a little researching around first gave me the jist of it. My problem, however, is that because of these codes, my car doesn't always start up on the first try, and that's not something that I need out of my daily driver that I deliver food in. They said they cleared them, but when they turned the car back on to move it, they codes came right back. All in all, I guess I'm looking for a solution to make my Z reliable enough to get me through the next 6 months-1 year before I have a different daily so I can really get going on the project, and get these codes cleared.

 

Also, as far as mods go, so far I only have :

NRG Quick Release Wheel - Which I believe to be the cause of the ASCD code, but the thing is, it shouldn't be thrown in the first place as the kit came with something to prevent it.
K&N Short Ram Air Intake - MAF is undamaged, and should be perfectly clean (I am checking this to confirm as this may be the reason for the Intake Air Temp code, but I also don't have another $70 to spend to just get my codes checked and cleared again in case it comes right back)
Muffler Delete, replaced with 4" piping - Shouldn't affect anything here

Otherwise, unsure about the NATS malfunction, even though this has happened in the past. Pretty sure it was just cleared and didn't come back. But now, it's coming back after being cleared and preventing the engine from turning over on start up occasionally. Thank you in advance to anyone who can help out!

why not try reinstalling the steering wheel and see if that clears up the top two codes along with your starting problem?

quick release wheel may be cool but starting your car is even cooler.

 

my friends are coming over with their tools tomorrow and we're going to be wrenching around on it checking everything out all day saturday as well as addressing other problems i've been having with my car. i'll definitely start here, thank god i kept the original steering wheel.

 

It's good to have friends, eh??? good luck Man
