My engine got hydrolocked and I got a new engine put in, now my rpm's are bouncing nowhere near as much power. Engine lights on and says 92a00 which is bank 1sensor 2 which I changed, but nothing is working. I bought a new cold air intake cause they told me to. Did not help. Told me to get a new mass air flow sensor, did not help. Any ideas on what it could be? When I am stopped it breaths weird and the rpm's bounce.

Hey MATTY22,

I think you have a vacuum leak, please follow the guide below to see if you get any results, check around the intake manifold gasket.

We tried that already and couldn't find a leak anywhere.

It could be a problem with an exhaust leak or the sensor itself is bad. It is the second sensor behind the catalytic converter. Do you hear any leaks while the engine is running?
