Check the MAP sensor.
"Yes. its a maf sensor (mass air flow sensor) and it will not let it start it will mostly just crank n crank over or start for a min with spiradic idling n shut off" Actually, there is such thing as a MAP sensor (manifold absolute pressure) but in some vehicles (especially Chrysler-Daimler) i believe, it can make the vehicle not start.
check the crank shaft sensor MAP, CRANKSHAFT, CAMSHAFT SENSOR THE COMBINATION OF THOSE SENSORS WILL LET THE CAR RUN RIGHT AND NOT STALL ANY MORE
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.
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.
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.
You need to clear the codes with a engine scanner.
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.
Crank and or Cam sensors may be bad. I would Buy both and try the Crank sensor first.
