Default 2007 CX-7 Dies under Load

Hello,
I have a 2007 CX-7. It will crank up fine and idle. When you put it under load it dies. I can turn the steering wheel, it dies (will not crank back up until I straighten the wheel), put it in gear it dies. I have replaced the crankshaft sensor, camshaft sensor, Put in new plugs and took the throttle body off and cleaned it thoroughly.

Have you scanned it for fault codes?

yes. One time it gave me the crankshaft sensor code and I changed it. It has been doing this for Several months and at first it didn’t give me any codes and now it doesn’t have any codes.

on the scanner (it’s one that is an app on my phone) the O2 sensor 1 is always at 0.00. No matter how high I take the rpms to, it never changes.

You definitely need to diagnose the O2 sensors.
