Default New to the forum. Map issue. 2.4. 4 cylinder 2003

Im having a MAP issue. The car is running off
, missfire and no power. The reading is stating:
Bad MAP sensor
Running rich.
I replaced the MAP sensor. I just changed the plugs and valve cover gasket. But still running bad. Any ideas?

What chassis/engine/ECU/harness etc..?

Make sure your IACV and MAP harness plugs are not reversed. Check MAP voltage and compare it to the service manual's voltage requirement.

Thank you all for your response. I found the issue. It was the catalytic converter. I had one installed today. Runs great.
