Question about Cars & Trucks
New fuel and air filters new plugs and leads
O2 sensors are what controls the fuel air mixture on a fuel injected engine. You will find them on the exhaust. They are attached to the wires that seem attached to your exhaust pipes under the car. Should be a 15\16 or a 22mm. You will need an open ended wrench for this task.

SOURCE: we have the same prob
plugged air filter will result in too lean.not too rich. have the fuel pressure tested. overfuelling will result in the catalytic converter overheating.if the 02 sensor on the catalytic is no good,it will not sense unburnt fuel and the ecu will overfuel. check the air inlet hose and the airflow meter

transmission slipping dragging brakes.timing off worn timing belt .bad spark plugs + wires +coil.defected valves and worn cam shaft.use scanner to check oxygen sensor. run engine 5 minutes look at scanner . should read closed loop . if read open loop replace oxygen sensor.

get your car diagnosed by OBD tool. you have sensors malfunction. may be oxygen or coolant sensor. check MAP also. does the smoke smell fuel. then your car is running on rich cycle.
