03 trailblazer 4.2 l code p0172 has no power


P0172 02 sensor is detecting that the system is running too rich. An 02 sensor that is starting to go out will pull this code, but the following will cause the 02 sensor to throw this code as well:

A few things to look at. 1st thing I'd do is clean your throttle body with the battery disconnected. Use sensor safe throttle body cleaner, about $4.

From there, I'd look at your upstream 02 sensor, located on the exhaust manifold on passenger side of engine, very easy. Try and stay away from Bosch if possible.

New fuel filter, clean or replace your MAF sensor located on top of engine next to firewall. Also, probably time to change your spark plugs. I recommend A/C Delco 41-103, will idle better than other brands.
