Hansandfranz is 1/2 correct; the car does need an "Idle Relearn", but, you do NOT need a scan tool for this. The vehicle just needs to be driven for the ECu to relearn the "base idle".
Get in, drive it down the highway. Do some passing gear downshifts. Pull off to the side of the road, let it idle for 30 seconds, repeat 2 more times. Then, try to duplicate some "in-town" (stop & go") driving, for about 15 minutes.
This will reset the "base idle", and your stalling condition will disappear. Expect to have to do this again if you replace the battery. Very common; the Computer (ECU) loses the base idle parameters when the battery is disconnected. Easily rectified just by driving as mentioned above. Feel free to comment back if you have any other questions.

Sounds like the engine computer needs to perform an idle relearn. don't think that this can be done without a scan tool

I have 1991 toyota pickup will crank but won't idle


Try this.

Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. 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

2004nissian maxima..replace po435..now the battery and brake light turn on and my cars dies


Quick way to see if your alternator is bad is to start the engine and let it idle. Then, while idling, turn on the lights. If the car dies right away or if it dies shortly after your alternator is bad.

Whenever i put my blazer in gear it dies


I'm assuming it's the 2.8, I'm not sure when they started putting the 4.3 V6 in them.
Anyway, a few things come to mind when something won't idle.1. EGR valves. If they are open at idle, it won't idle. It's open at cruising speeds when the engine is warm, but not at idle or full throttle.
2. Idle air controller (IAC): This is a little electrical valve located on the side of the throttle body. It regulates the amount of air that the engine needs to idle at the correct speed. It makes up for stuff like cold temps, being in gear, or having the A/C on at idle. They also get full of junk and jam up, or simply fail electrically. Replacement is extremely simple.
3. Ignition timing. If the timing is late (********), engine vacuum is lowered and it struggles to idle, even without the load of a transmission in gear.
4. Vacuum leaks. Crunchy old vacuum hoses make everything worse.

Stop on stop sign engine died


If the engine won't fire up, but your starter turns over, you may want to check your timing unless you have a check engine light on. If the CEL light is on, have the codes scanned.

If the engine won't turn over with the starter or it clicks, have your battery tested at autozone or advanced auto parts. Replace the battery if it is bad. Else, have your starter tested.

If the engine still won't turn over and the battery and starter are tested fine, you may have a blown fuse, bad ignition switch, or a failed relay.

If the engine fires up but randomly dies and starts back up, you either have a failed sensor, failing fuel pump, clogged fuel filter, bad plugs or wires, or a failing ECU.

I have a 2004 pontiac sunfire with a few problems. First, when I turn the ignition to start the car all I get is a fast-paced clicking sound from the dash area and the engine doesnt even turn over. This...


as fo the idle, there is a IAC ( idle air control to maintain idle. you may have to remove this and clean the carbon out of it, and the intake as well. as for the clicking there are 3 solutions to fix it. battery if it is ok, the solinoid is bad on starter or the starter itself. but it does sound like a bad starter solinoid, because a bad battery will make the same clicking from solinoid. but make sure battery is ok first. when engine is off voltage at battery should be at least 12.6 or better. when running and alternator is ok, it should read about 14.2 to 14.7 if lower then 14 volts alt. is bad. have a very good day !! hope this helps!

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.
