How will a bad map sensor make truck run


that is what it does, it senses the amount of air flow to engine, clean filter, it may be a simple as that

Stalls after start up, Stalls when braking, then runs fine after a few minutes


Check the ECU engine temperature sensor. If it thinks the engine is hot, it will struggle to run when cold.

Car hiccups and stalls


Although your temperature gauge may show that it works, some models have a second temperature sensor for the engine management system.
That second sensor provides info which sets curb idle and timing advance. The "Cold start" feature is a part of this. The hic-cup is something of a bucking symptom as the engine controls toggle between hot and cold run settings repeatedly as water temperature is not stable.
In the past, I found several 1984 engines having defective thermostats which are tied into "Step-up" solenoids for the curb idle. What happens is idle speed is suppose to drop when the engine is hot.
When someone adjusts the curb idle while the engine is on the "cold setting", the setting(rpm) will be too low once the engine has heated up and the part drops to a hot setting.
So to clearly define your problem, you have 2 stemming from the same defects. The "in motion" problem is caused by timing changes based on temperature and the "idle" problem is caused by improper adjustment of the curb idle solenoid because of unstable operating temperature.
What you want to do is change your thermostat. This will give you a stable temperature. Then let the engine heat up and you should notice a "click" and the engine should idle down. It may stall. Then turn the idle rpm up until the engine will not stall.
The hic-cups should disappear once the operating temp is reached. If you still have problems then look for the water temperature sensors before replacing expensive parts.

2003 Toyota Camry 166000 mi., 2.4 liter 4 cylinder. ONLY WHEN CAR IS HOT, idle drops off, engine stalls, must step on accelerator to keep from stalling. Otherwise, idles normally. New spark plugs,...


Some "check engine" light in your dashboard? If YES, need to scanned the PCM (computer) to know exactly what fault code is stored there. If NO, the crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

Also, keep in mind that on the 2.7L V6 and 2.4L 4 cylinder, a defective Exhaust Gas Recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Stalling synthoms... you can have a plugged exhaust, plugged fuel filter, bad airflow meter, problem with the ignition system, incorrect timing belt/chain setting, and failing fuel pump....I'm sure there's more but that should get you thinking.

Keep us updated.

My dodge dakota it idles below 1000 rpms and it sounds like its about to stall. and if i rev it up and then let off it will stall instantly. when i am driving from first gear to second it goes up to 4000...


It is actually hard to say without actually seeing the vehicle, but the target speed for your engine idle is around 750 RPM. The stalling after revving kind of depends on how high you are revving it and whether the engine is at operating temperature or not. This may be normal. Then again, it could be that the Idle Air Control (IAC) is not working properly.

The shifting from first to second at 4000 RPM sounds like a completely separate problem. This could be due to low transmission fluid level, sticking shift control solenoids, or possibly even a malfunctioning Vehicle Speed Sensor.

If the Check Engine light is on, have that checked first.

Would a bad oxygen sensor on my 1996 ford explorer cause my engine to die after driving it a distance?


no, the only way an O2 sensor might cause the engine to stall is if the heater shorted out with the power supply and every time we have seen that the engine will not run at all. if you have a stall hot check the idle control motor the year is right for a bad one.....HAVE FUN

I have a 1991 Buick Park Avenue. Runs rough in


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, 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.

Throttle/Idle/running problem - wants to run too fast, or stall out


RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.
