I have a 97 grand caravan 3.0 3spd trans, my van stalls from time to time also i get a po300 code. I have changed the tps,iac,crankshaft sensor,coolant sensor,vss,cap,rotor,wires,pvc,thermostat,o2 (both of them),fuel pump and filter, fuel pump relay, and asd relay..... I am at a loss the van runs like a champ then out of left feild it starts to stumble and then it dies out. I try to start it and it will run for a few seconds and dies. Or it will start and idle fine but i put it into gear and it will die out. If i get it started and i punch it a few times it seems like the problem will go away most of the time. Would a semi blocked cat do this? Any sugestion would be great.
Thanks
Bill

 

hey bill. i'm going to move this over to the caravan forum for you. welcome to DF!

 

the ONLY code is p0300?
no remote starter or aftermarket alarm?

can do a simple vacuum ck for a bad cat ..... but you should ALWAYS have the issue not intermittant. Can you add anything about the stalling
Only happens at stops- slowing down...radio/accesories also go dead...confirm a 3sp....no OD?

 

Hi Bill
A semi blocked cat would give you lack of power,and you would noticed that. Is the van stalling went you are coming to a stop or stalling from a stop? Also are you hearing grinding noise when starting. That could be a flex plate cracked and also cause a multi-misfire(P0300). Leonard
