Default 370z HELP

I'm kind of clueless now. I need your guys' help.

I have a 2010 370z Twin Turbo with about 35k miles. Car has been running great. Recently replaced clutch and flywheel. All maintenance has been performed on time as well.

Details:

Recently, car has been sputtering, feels like misfire. Pop coming out of the exhaust when driving and can actually hear the sputter just during idle. Car threw a cel. It was P2A00. Bank 1 Air fuel sensor 1. In all, it drives rough now and has complete loss of power. I've checked the coils and the plugs. I'm doing a compression test later to find out if it can be a valve or piston. Any other ideas?

Thanks a ton guys

Did you replace the sensor the code pointed you toward? A new O2 sensor could conceivably cause everything you've described.

I would check to make sure all sensors are plugged all the way in/threaded all the way. Also, check all hoses.

The previous owner replaced the sensor, that sensor is newer than my other ones.

O2 sensors can go bad. It's cheaper and easier to replace that and see if the problems go away than going too much further down the rabbit hole.

An exhaust leak can throw a P2A00.

Yeap, What TT kit is it? If it is a GTM kit they are known for cracking exhaust
manifolds.

Did this happen after the clutch install? There's a crank position sensor tucked up behind the downpipe that gets crispy with the turbo heat, and can easily be fubar'd during the clutch install.

I fried my crank sensor and the car would not start at all. What are your afr's doing? It could be a bad injector. What tunning package do you have? If you have ecutek you can check to see if it is an injector by disabling each cylinder in sequence. You disable cylinder 1 and it should run like it is on 5 cylinders, then enable 1 and disable 2 and so on. If you disable a cylinder and there is no change in the way the motor is running then that is your bad cylinder or injector. This also happened to me and the car ran as you have described.

Thanks for all the advice. Please keep them coming.

I am running the GTM kit. I do have a leak coming from my catalytic converter. Once I pass emissions I’m going to get test pipes. I have an Uprev tune so I can’t try the ECUtek way but checking the injectors is my next step. If it was my guess it could be something fuel related or a cracked exhaust manifold.

My air fuel ratios are showing that I’m running lean on heavy throttle. I’m also going to check my crank position sensor.

Fix the exhaust leak and get a new 02 sensor first. That's the most likely reason for what you're dealing with.

Edit - are you running stock cats? They could be plugged up. They don't like turbos.

Also, from what my mechanic is saying is that it's isolated to one cylinder which is cylinder 1. Something is going on with that cylinder.
