SOURCE: o2 sensors on a 99 mercury cougar v6

I just got done replacing the O2 sensors in my 99 Cougar due to throwing a P0135 malfunction code. There's 3. Facing the engine there's one in the front coming off of the front header, which is easy to get to. Another more tricky one if between the engine and the fire wall on the rear header pipe. The third is under the vehicle behind the transmission pan on top of the exhaust. In order to replace the O2 sensor near the fire wall you will need to remove the 4 retaining bolts for the ECM module and move it out of the way. Additionally you will need to remove the 2 retaining nuts for a wiring harness that is seated below the ECM module. Pay close attention to the connectors because the front and under vehicle O2 sensors have round connectors the one near the firewall has a squared connector. I was able to replace all 3 by myself in approximately 35 minutes. If your throwing a O2 heater malfunction code it is most likely going to be the sensor near the firewall. make sure that you know someone with a code reader so the code can be cleared. If you're do for an emmissions inspection be sure to put at least 40 miles on the new O2 sensor with different types of driving (e.g. highway, coasting, decellerated turns and rapid acceleration). Gotta love project cars for your kids!!

I would use 10W40 in the 96 and 5W20 or 30 in the 2002.

For the 96 with sluggishness, you need to gently clean the MAF sensor wires with carb cleaner and a toothbrush. It is in the air intake tube. After cleaning, disconnect the battery for 1/2 hour, then reconnect so the computer can relearn the clean sensor. Drive for 10 miles, it will run rough until it relearns.

Section 03-14: Engine Controls, Electronic 1996 Town Car, Crown Victoria, Grand Marquis Workshop Manual
DESCRIPTION AND OPERATION Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579):
  • is mounted on the corner of the engine air cleaner (ACL) (9600).
  • uses a hot wire sensing element to measure the amount of air entering the engine; air passing over the hot wire causes it to cool.
  • sends out an analog voltage signal to the PCM (12A650) to determine the intake air mass. The PCM will then calculate the required fuel injector pulse width to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

My mercuy villager wont start it trys to turn over but dies when i press the gas its a 1996 mercury villager gs

Will it idle ok? When it warms up, does it run ok? Sounds like a couplf likely things.
The fuel pumpcould be getting wea and not supplying enough pressure (40 psi) to the fuel injectors. Pump is in tank. About a $200 repair.
The fuel misture could be too lean due to a thin coating of varnish on the MAF sensor (mass air flow). It is on the black air cleaner tube held in with 2 anti tamper screws. Remove it and cean the wires with carb cleaner and a tooth brush very gently so you don't damage the delicate wires. I think you can get access by removing the air cleaner intake hose it is mounte on. About 3 inches x 4 inches. Also, clean the honeycomb air diffuser inside the air cleaner tube.
Other possibilities are dirty injectors, or other bad sensors. Need more info on how this started happening, how does it run warm, and if the comuter has fault codes. Your local auto parts store might run the computer test with their scan tool for free. Ask them.
Do not buy a knock sensor since they are never bad but the test sometimes says it is.
good luck. let us know what happens.
