1995 1500 5.2 is getting a lot of gas in the oil. It will idle fine, but when it warms up it will stall out. It will have a lot of unburned fuel. I have replaced IAC, MAP, TPS, TEMP Sensor, Crank Sensor, Fuel Pump, new plugs and wires. Could the O2 Sensor cause this problem? Checked codes and it still shows a code #25, after I put in the new IAC? Please help!

 

it could be the O2 sensor calling for more fuel, or it could be a leaking injector dumping it into one cylinder. was any one spark plug a lot worse looking than the others? is MPG bad or worse than normal? you might do a compression check to rule out anything bad.
