2004 chrysler pacifica issues with stalling, idle speeds up and dies out to almost stall

Randomly this car will stall for no reason. When driving the rpm will raise up for no reason then go right back to normal. At times it will act like it is going to stall out but it comes right out of it. Sometimes for days it will act up then nothing for weeks or days. We have had loads of work done to this car and nothing has worked. No codes or lights come up on the dash. My mechanic has tried to run diagnostics but nothing comes up.

well, the power steering will freeze when the motor is not running. the mechanic may not find what seems to be the problem specially when no warning lights are coming. you can try replacing the fuel cervo and this will surely help. not everyone knows about this.

When I drive my car and come to a stop the lights flicker and I have a idle under 1 I have a new battery nothing is wrong with alternator and it feels like car wants to shut off 2005 chrysler pacifica

The cars idling speed is too slow. Then the alternator cannot produce enough voltage to power any electrical devices. The idling air control valve is dirty or defective. You are lucky that the car has not stalled out yet.

My 04 chrysler pacifica cut off when driving or at stop light. what could make it do that?

You should have the computer scanned for trouble codes first. The codes may point you in the right direction to look for the problem.
Common causes for stalling is a dirty throttle body or faulty idle air control valve among other things.
Let me know what the codes are.

Hello Paul, You stated your crossfire stalls and the usually restarts. It could be several things that cause this...

Check the fuel filter on car for a restriction. Check the air filter for a restriction(dirty). also check the IAC valve (idle/air/control) located on the side of the throttle body. To check the iac valve, start the engine and disconnect the electrical plug from the iac. Listen for a change in the idle of the engine. then reconnect the plug to the iac valve and turn on the a/c and listen for the engine idle speed to change. If not then replace the iac valve. Hope this will help you.

One suggestion:
Speed sensor failure.

Some of the classic symptoms, stalling at dead stops. failure to auto lock doors. poor fuel economy. Failure to go to overdrive.

Go to your local parts store and run the failure codes.

Shop notes:
Your ECU thinks that the engine is running with out moving, During slow down the engine steps down the idle to match ground speed and as a result the engine will not stall. At present it goes directly to idle and stalls due to drag on motor.
Hope this tip helps.

When I slow down to a complete stop, my 1999 chrysler sebring cuts off. Can you help me?

Possibly a transmission issue. The transmission has a "lockup" mode, where a clutch connects the engine directly to the transmission at cruising speeds. It is then supposed to unlock at lower speeds and for stopping. If it doesn't unlock, the car will stall at a stop. Try putting it into neutral (carefullly, so you don't go into reverse) as you slow down, if it doesn't stall out, it is most likely the transmission lockup mechanism.

If it stalls in neutral it is an engine issue. Bad idle control, bad ignition (it's easier to fire at high speed), bad fuel injector, bad air flow/pressure sensor... and more possibilities.
