yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.
Check your map sensor
The location of the map sensor depends on what year of which model car you are asking about.
The MAP sensor is on top of the throttle body. as you are looking at the engine from the front of the car, it is on the right side of the engine. The sensor says "MAP Sensor" on the top of it. very convenient.
You can not prevent a sensor from failing.
On the firewall on the right side. if the car is 3.3l v6 then the car doesn't have a map sensor but it does have a mass air flow sensor the code is the same for both of them only a 2.3 has the map sensor so don't be fooled by this by code 34 the chilton book is very helpful
The 91 has the 4.6L engine and has a MAF sensor located just after the air filter box so it has no MAP sensor.
It will be smoking black out of the exhaust / Running RICH. Spark plugs will be fouled out/ Black. Replace them if it is running rich. Plugs will not fix your problem. Replace map sensor.
The MAP sensor measures air flow for your car's computer. The computer uses air flow to set fuel flow for the correct fuel/air mixture.
no need for map sensor enhancers on cars before 1996...
The MAP sensor ( Manifold Absolute Pressure sensor) sends the correct internal pressure to the ECU for the proper fuel/air mixture.
Possibly a MAP sensor issue. the MAP sensor limits RPM's to 2k. If that sounds like the problem, look at the vacuum hoses to the sensor. MAP sensor is located on the left strut tower looking at the engine.
