Want this question answered?
No. However it can affect the idle and power. It will affect the air-fuel mixture resulting in an increase in emissions and gas mileage.
Code 33: Mass air flow (MAF) sensor Signal voltage or frequency is high during engine idle OR Manifold absolute pressure (MAP) sensor Signal voltage is high during engine idle. Engine misfire or unstable idle may cause this code.
the choke is on
A 95 does not have a idle air tempture sensor, It was not used on that year, no need for one.
Possible o2 sensor
The idle shutdown mechanism depends on how the ECM is set up... there are many ways this can be done. Running it at high idle might or might not override the idle shutdown, dependent on how the parameters are set. If you have ambient air temperature override, you can tape a hand warmer to the temperature sensor.
May be idle position sensor.
No it will not. It only controlls the idle of the engine.
mass air flow sensor could be going bad
The IAT ( idle air temperature ) sensor is built in to the MAF ( mass air flow ) sensor.
MAF(Mass Air Flow) sensor, TPS(Throttle position sensor) sensor, IAF(Intake air flow) sensor, EGR, leaking, loose or missing vacum hoses...
No, the MAF measures the amount of air entering the engine, while the idle control valve controls the amount of air at idle.
