The MASS Air Flow sensor can certainly cause a problem if it's not functioning properly, but you should connect it, then run engine diagnostics to see what the COMPUTER says is wrong. Here are a couple prices for a MAF sensor for a 92 Lincoln Town Car, don't know if it's the same model as yours. http://www.partsamerica.com/ProductList.aspx?parttype=473&ptset=A&searchfor=Air+Flow+Meter%2fMass+Air+Sensor
crankshaft sensor going.
throttle posistion sensor or vacuum leak
If a car starts and idles but does not accelerate can be numerous problems such as a malfunctioning throttle position sensor, fuel regulator, Manifold Airflow sensor or vacuum leak. A diagnostics test will reveal what is malfunctioning and needs to be repaired.
Most likely its not your mass air flow sensor its gonna be your tp sensor (throttle position) or your down stream oxygen sensor because a MAF sensor controls your ITS or Ideal temp sensor witch can affect your accel and your idle when under a load but when its at rest or idle it will be affected by a tp sensor of O2 sensor they call the O2 sensor the spark plug that never gets changed..
I had the same problem on my 98 Mazda 626 and the O2 sensor was faulty.....
id change the coolant temp sensor
Did they replace the MAP sensor? If not, good chance there's your problem.
I changed my tps sensor on my 2001 Dakota and it solved this problem.
Not adjustable. Sounds like the throttle position sensor.
Is the gas milieage ok, check bad grounds Mine has a bad O2 sensor, does the same thing. Does It take gas when you first start it and try to take off?
Throttle linkage could be in a bind or TPS is defective. (throttle Position sensor)
see previous answers, but if it idles high it might be the Mass Airflow Sensor. if your car idles too high for too long and you keep driving it, you could burn out the transmission module (very expensive )
You might need to change your throttle position sensor.
Could be the Throttle Positioning Sensor or the Idle Air Control Valve
Check fuel filter and fuel pump.
That is usually something like a map sensor, throttle position sensor, EGR valve or who knows what. Run a computer diagnostic scan to find out which might be causing problems for you.
I believe its the Throttle Positioning Sensor is out of test range. I took it to the shop, they fixed it. He told me it was some sensor, my car now idles normal. So yeah that is what is most likely.
it could be the idle speed sensor located on throttle body however i replaced mine and it still idles high. The code indicates lean air/gas mixture so i am still looking for small vacumm leak
its most likely your idle control sensor. if you replace it the truck should run fine.
replace the thing its faulty dont try do fix something you dont understand
My '95 did the same thing. It was the Throttle position sensor.
Have the computer scanned for trouble codes. The problem may be a bad Throttle Position Sensor (TPS) or Idle Control Valve (ICV).
O2 sensor(s) needs replaced.
TPS or idle air. ------------ ECT is a far more likely cause of cold running problems which stands for the Engine Coolant Temperature sensor. Also check the IAT or Idle Air Temerature sensor. A scan would be the best course of action at this point if you suspect a sensor problem.
You may have a faulty coil. Check mass air flow sensor
