The van is not accelerating immediately but with a delay, after pressing gas

There could be many, actually. How long has it been since you've cleaned the fuel system? Depending on miles, might not be a bad place to start. Always work on the simplist things first so you don't ramp up costs too quickly. Any will do, but I typically use seafoam at least 2-3 times a year and I notice a significant difference in performance in all of my vehicles. Depending on when your last tune up was, that could be part of it too.

about 38000 miles. I've never cleaned the fuel system. Is that recommended on a vehicle like mine - about 3 years old,38K miles? What other things do I look for ? Thanks for your response .

It never used to be something you needed to do regularly, but with all the nonsense they put in fuel, its definitely worth it. I do it pretty much around the time I do oil changes and since I run full synthetic in all of my vehicles, I usually do it every 7-10k miles. What you look for will vary from vehicle to vehicle and symptom to symtom. I'd start off running Seafoam and check your air filter. You can easily do this yourself on most vehicles without paying the $40+ most places charge. Refer to this video for an idea of where and what you're looking at. https://www.youtube.com/watch?v=SQDsl49ZUV8 Beyond that, depending on when the last tune up was, you may start treading into territory of changing plugs/wires and other tune up specific items. I'd refer to your manual for the exact timeframe of when you should do your tune up as practically every vehicle is different in that area.

That was useful. Thanks. Will start with the air filter and sea foam.

Cool. That should definitely start you off on the right path. Those are the two simplist items that have a huge impact on performance. You should even see a fuel mpg increase after both are handled.

Dodge Grand caravan ECU is very slow this is a known issue my 2015 has about 20,000 miles on it and the throttle must have a full 3/4 second delay before the engine engages I've had vallet people tell me there's something going on with my pedal I've tested several other Grand caravans are all the same.

Hi DWYS. I also have a 2017 Caravan with only 12,000 kms. and it has that acceleration hesitation. It's very annoying as it sometimes causes me to spin the tires when I pull out into traffic. So, in your experience, do you think it is a 'fault' in all the Caravans now ? And do you know of a possible fix, maybe even on warranty ? Thanks, Dano

I have spoken to four Dodge dealership service techs. There is a delay in most all Dodge pedals. You have to press the pedal very slow otherwise you will over throttle. I put a piece of hard sponge under the gas pedal and it helped me feel when it was beginning to move as I accelerated. This helped a lot !!!!

I bought 2016 dodge grand caravan from the dealer ship. The dodge grand caravan really takes time to accelerate on the low speed.The mechanic and auto delership are not agreeing with me and telling me put more gas :).
