okay I was just driving my car this mornin and before I stepped on it to get into boost, I hear a small pop(sounds like it came from the engine bay) then m check engine light comes on. So I pull the code to find out it was the p2097, so figuring I would get rid of it I reset the pcm, but nowwhen I get into boost my car stutters then goes? what the hell is going on and how do I fix it?
P2097-DOWN STREAM FUEL SYSTEM 1/2 RICH
When Monitored: With the engine running in closed loop mode, the ambient/battery
temperature above (-7°C)20°F and altitude below 8500 ft.
Set Condition: If the PCM adds downstream short term compensation to long term
adaptive and a certain percentage is exceeded for two trips, a freeze frame is stored, the
MIL illuminates and a trouble code is stored.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
EXHAUST LEAK
ENGINE MECHANICAL PROBLEM
O2 SENSOR
O2 SIGNAL CIRCUIT
O2 RETURN CIRCUIT
FUEL CONTAMINATION
276
DRIVEABILITY

Well this past weekend I did the tip mod, and it seem to fix the car, but now on another note I'm spiking 19 and holding 12lbs and am runing pig rich off my aem wideband. So time to do somemore tinkering

Re-gap the plugs.
ima redo them this weekend I think there set at .45
You running over 20psi boost? If so you might need to lower your spark plug gap...
no, he's running stock boost. I bet it's an exhaust leak or the o2 sensor.
Stock boost hahahaha try 22 psi spike holding 13, after we put the ported turbo and I redid his spring mod now he's at 18 spike holding 15 mucho better
