Could bad maf sensor and bad idle air valve have vehicle stall then hard to start for awhile and cuts off after 10 minutes of driving

It seems like the problem lies with the engine management system, rather than the brakes. Given that you've already replaced the MAF, MAP, and TPS sensors, here are some other things to check:

1. Vacuum leaks: Inspect all vacuum lines for cracks or damage that may be causing a leak. A vacuum leak can cause erratic idling, poor acceleration, and stalling.

2. Idle air control (IAC) valve: The IAC valve controls the engine's idle speed. A malfunctioning IAC valve can cause the engine to stall during idling. Try cleaning the IAC valve with carburetor cleaner and see if the issue is resolved.

P0103 OBD-II Trouble Code Technical Description Mass Air Flow (MAF) Circuit High Input What does that mean? Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104. Symptoms You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness. Causes A code P0103 may mean that one or more of the following has happened: The MAF may be disconnected, or a wiring connection may be bad The MAF sensor may be damaged The vehicle computer may be faulty (very rare) Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor. Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.

Let the vehicle warm up for 10 minutes at idle and shift it to Reverse if the RPM bumps up thats fine but if it dosent then replace the IAC idler air control valve.

Jeff did you figure this out. I am dealing with the exact same thing currently. Things to look at are Mass Air Flow Sensor (MAF), Throttle position Sensor (TPS), Air Idle control valve. I have played with everything but the Air control valve. I tried three different MAF, including a ghost sensor (circuit to match ressitance). I'm going to investigate the air idle control tommorrow. Let me know if this helps or if you get it figured oot

no timing belt on the particular vehicle. but yes probably something minor, check fuel pressure, fuel pressure regulator, MAF sensor and IAC motor. all these can cause intermitent stalls. The MAF is located somewhere between the air filter and the throttle body. it is a sensor that sometimes gets dirty with air particles and will affect fuel managment. the IAC motor is on the throttle body and if gets stuck with carbon will not be able to control idle. the fuel pressure regulator is on the fuel rail and if the vacuum line is filled with gas then the diaphram is bad. and the fuel pressure should be 35 to 50 PSI running.

I would start by cleaning the inside of the Mass Air Flow sensor, dirt gets on the sensor element from the air going through and causes these kinds of problems, a company called CRC makes the spray cleaner for MAF's, any good auto parts store will have it, the MAF is located in the air intake hose to the engine. Another thing to check is the throttle valve and air bypass idle speed control valve for sludge, use the following procedure I have written to perform this.
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
