Hello, I'm having trouble with my S197 2006 V6 mustang as all four O2 sensors are stuck on rich and coupled with this is the fact that it runs horribly and spews unburned gas and carbon particles from both exhaust pipes (aftermarket).
Help! Car Running Rich!
I've replaced the spark plugs, both upstream O2 sensors, coil pack, spark plug wires, fuel pressure regulator, MAF sensor, fuel injectors, & cleaned all of the sensor pins and connectors with electrical cleaning spray including the PCM.
The freeze frame data provided was while the car was idling with the foot off of the throttle:

OK, something is not adding up here........
Re: Help! Car Running Rich!
You have full rich 0/2 sensor readings yet the long and short term adaptives all read 0. Had you just cleared the computer or something? The computer is doing nothing to correct this condition.
The other thing is how long had it been running because the temp only reads 131 degrees.
