HI I have a 1997 pickup that runs rough, stalls when idling and stalls when stopping for any reason...I get a mass air flow sensor code when its read but it has been replaced twice and problem is still not resolved. The idle air control valve tests out good and there are no broken hoses or vacuum leaks...also the throttle body has been cleaned. I am at a loss.
Hi,it might be that the ecu is still thinking that the mass air flow sensor has still got a falt as the falt was not removed from it,and another thing you could have a look at if it has one is frottle position sensor,just food for thought hope you sort it.
Undo your battery overnight so the computer will reset and see if that helps.if it does not you will probably have to take it to an auto parts store and see if they can reset it
SOURCE: car stalls at idle
sounds like you need a tune up. Starter starts the car alternater keeps the battery charged up to keep the car running. Try a new fuel filter maybe some fuel treatment also
SOURCE: a p0011 code and camshaft sensor replacement did not cure problem
well i know on the v6 that is true you replaced all of them. Not sure of 4 cyl but seems like it should be the same. Also I know on the v6 the variable valve timing set up sometimes did some weird failures triggering a cam sensor code. It could be anything from sludgy oil hanging up in the vvt hub or clogged passages or bad solenoids. but before going into all that(well besides maybe an oil change) I would go for the crank sensor.

It has been my experience that this problem is usually caused by a dirty or bad Idle Air Control Valve (IACV). I would try removing the IACV and cleaning it thoroughly, as well as the air passages in the intake manifold.
You can check the valve itself. Check the resistance between the two terminals with an ohmmeter. The resistance should be approximately 10 ohms at 77°F. Also make sure the plunger moves in and out without sticking or binding and the spring is not broken.
OK now the bad news, the (IACV) is at the back of the engine and up against the fire wall. Lots of bad words will be used to replacing this and i think the dealer charges $550.00 in labour alone.
You can try running Sea Foam through the manifold, just follow the instructions and there will be lots of smoke, Do a search on You Tube for Sea Foam. You can try blasting it with throttle body cleaner though a vacuum tube and down the throttle body, may have to use three cans, just follow the instruction again.
Good luck and keep me posted.

it soubds like you have a vacum leak problem listen for a "his" with the engine running. you may want to take apiece of hose @2-3ft long put one end at you ear and probe arround the top of the engine arrount the intake manafold and any hoses when you find the his find wher it goes and replace repair the hose. it may also be your pcvvalve thst is stuck it willcome out of the top of your valve cover and plug right the intake hose right before the throttle body

Let's try the cheapest fix first. Change the fuel filter out. You'll probably see a brown looking goop in the gas, This is an "ETHANOL" problem. Read up on it. These are all related to so many idle and acceleration problems. Buy a can of SEAFOAM at the parts house. Fill up tank with Premium and add SEAFOAM. Then change filter out before 500 more miles. This should clean out the water and the goop and the carbon build up caused by the ETHANOL. Add a can of SEAFOAM every 3000 mile after that to a full tank of gas. It will keep your emissions,engine, and fuel lines clean. And will keep your car from line freeze up. Good luck.
It
can be low fuel pressure issue or clogged fuel pump. Or its engine related

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
