Question about 2000 Lincoln LS
There could be a few things causing this to happen.
1. Replace air filter and fuel filter. If it still dies when put into drive:
2. Start the car - open hood. Find Mass Airflow Sensor (located between intake manifold and the air intake line (large plastic hose that runs from front of car and into intake manifold). It is a small (usually black) box looking unit. It should have a wiring harness that connects to it.
3.With a wrench or screwdriver handle, (car idling) tap the top of this. Not too hard; but hard enough to "jolt it'. If the car stalls, the idle fluctuates or the car simply dies, this needs replaced. It is call the MAS (mass airflow sensor).
4. You can first buy some MAS cleaner, and see if that helps. If not, replace the unit.
5. It the car idles normal while tapping, the unit is fine, but cleaning it will do the car some good. Go to your local parts dealer and purchase the cleaner for it. (this isn't a must)
6. If replacing the air filter and fuel filter does not change this issue, then change the O2 (oxygen) sensor(s). These will be located : 1. on the exhaust manifold just behind the engine (and down a bit) ; 2. Just behind the catalytic converter. There is a special socket for removing this, but if you cannot purchase one, (auto parts dealer) then just use the correct size open end wrench or Cresent Wrench<--not recommended, but will work in a need to basis.
The socket should cost around 15 bucks or so if I remember right, but again, not a must for this as an open end wrench will suffice.
If this does not help either, (and do this as a safe measure regardless of any outcome from above suggestions), check all the vacuum lines. One may be off, have a hole and need replaced.
Please let me know if you need any further assistance.
