It may be over heating,check out your rad hose. There are many things that can cause low power: weak fuel pump(check pressure), sensor malfunction ( codes ) ,charging system malfunction, transmission shifting issues, brakes dragging.
The rear air conditioner is a separate system. Dodge did a recall because some of the piping deteriorates and loses its charge. It sounds like you are experiencing something like that.
your block is cracked or there is a seal broke be careful if u are driving the care
No.
You need to have the ECM (engine computer), not the PCM, checked for trouble codes. You will then know what to diagnose.
Is the engine running ? no
Nope. It uses a relay, the ASD or Auto ShutDown relay. Basically it is fed off the distributor pulse in most cases so if the engine stops, the relay loses power and the fuel pump is shut down.
Bullitt
problem a vacuum leak
It sounds to me like you need to check the fuel filter, sometimes trash gets in it and when you tap on the gas it moves the trash out of the way for a few moments then it will start it again once the trash settles.
The Toyota Sienna , Ford Freestar both hold value well. The Sienna for about 7 Years and the Windstar for about 5-6 years. The Dodge Caravan loses value quickly. The Foreign seems to hold it better, and the Loaded Models seem to be easier to resell when your done with them than the base Models.
Clean them and see.
