P0132 is lean front sensor. Rear sensor should also then indicate lean. Check for damage or pinching of front sensor wires. Undo the connector, inspect and reseat. This four wire sensor, from what I can see, should not be sensitive to sensor gound issues, but there has been some conratictory info on that. If the sensor base has resistance to ground, reseat it or trace the location of the resistance in the exhaust system and reseat nuts or whatever it takes. Might not make any differnence, but you have already been doing that!

P1172, running too rich, ?short term? at adaption limits. Perhaps also a wiring problem as this contradicts the above code.

P0300, repeated misfiring, evap control valve stuck open or its hose busted, low fuel pressure (but then starting would be hard), bad DI or bad/wrong plugs, badly fouled injectors. Misfiring can create P1172. I would check the evap solenoid valve wires and hose. Perhaps remove the valve and clean it out. Some have reported sucess with WD-40. Other things may work well. Perhaps some residual lubrication is important as well.

P0125 indicates that the engine is not warming up fast enough. Can be a problem with the sensor or the T-stat. Have you done the 'feel for cold rad hose while warming up test'? Ice forming in coolant can do this if coolant has had a lot of water added to it.

Also check for exhaust leaks near the first O2 sensor. Any exhaust manifold studs missing? Any 'flash' marks on the head around the gasket?

So sensor and solenoid valve wires, solenoid valve hose, sensor base ground. Reinspect the plugs... they say clean or rich? Double check gap and look for defects or cracks in the insulators. Do you ever feel missing? Injectors known to be clean? T-stat works right. Engine temp indicator gets to 9'oclock and stays there ,never drops at highway speeds. If no relief that way, remove and reseat the ECU harness connector. Disconnect battery before doing that! Sometimes you have to try futile things as part of problem elimination. The contradictory codes suggest wiring faults or something out of control such as evap system.
