Re: 96 Grand Cherokee - Stalling... Replaced CPS .... Different stalling
 

What about a blocked gas tank vent? That will sure give your symptoms.

I don't know where it is on your vehicle, but if the air filter on the
bottom of my charcoal canister gets plugged with mud it puts a vacuum on
the gas tank and does a nasty immitation of running out of gas. Let it
sit for 10 minutes or so and away it goes again.

The fast test for this is to open the gas cap when it dies and see if it
starts right back up.

If it is, he can get some freeze spray from any electronics shop. When
it dies, give the coil a freeze spray shot and if it fires right back up
it is figured.

Re: 96 Grand Cherokee - Stalling... Replaced CPS .... Different stalling
 

I actually tried the coil thing. Instead of freeze spray, we took it
out, put it in a bucket of ice water for a while. Put it back in and
still no start up.
