My van stalls a lot will a bad oil cooler cause this Mechanic's Assistant: Is the check engine light on? Does the car stall at idle or when driving? No engine light but it shuts off when I come to a stop or sometimes when I start to drive but starts right back up Mechanic's Assistant: What is the make/model/year of your car? 2016 Dodge Grand [Caravan sxt](/topics-caravan-sxt/) Mechanic's Assistant: Are you fixing your Grand Caravan yourself? What have you tried so far? Took to dealership but they said they can’t find out what’s causing it Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I’ve rebuilt my transmission and I do know my bank 1 converter is bad just don’t know which one was told I have 2 of them so I don’t know we’ve spent so much money fixing this van over the past 4 months and still nothing

No an oil cooler will not cause a stalling issue. It will cause a bad leak and is very common with the 3.6 v6. A bad catalytic converter coud cause this though. If it is stopped up the engine can't breathe and will stall. Could be many other things though also. Crank sensor, fuel pump, wiring, PCM, ect.... only way to know is to have it on a scan tool when it happens and monitor some data to see what is happening.

Thanks for the information my van is currently at the dealership now and I'm confused as to why they can't find what's wrong
Automotive Expert
You are welcome glad to help. They probably can't duplicate it. Happens alot on cars but they just have to hook a scanner to it and drive it and make it act up and hope they capture what is going on.

At one time I had a code p0420 would that cause the constant stalling
Automotive Expert
That code is for a faulty catilytic converter, exhaust leak, faulty 02 sensor. It could cause stalling but the cat would have to be broken up and causing a restriction randomly and I just don't see that being the cause. It is probably a wiring issue. Here is what I would do. I would do a fuel pressure test with a gauge and drive it until it acts up and see if the fuel pressure drops. They are known for the fuel pump relay failing in the TIPM. This will check it.

Ok hopefully they do what you suggestedWithout me saying anything
Automotive Expert
Yea hopefully so but you could suggest it. Wont hurt.

Okay thanks

HI there. Yes, when the key is turned on any heated oxygen sensor will start to heat up. Most will not continue unless the engine is started. This depends on the vehicle application.
