Using Sea Foam to prevent stalling in my Dodge Caravan [SOLVED]

I have a 2008 Dodge Grand Caravan with a 4 liter engine and 253,000 miles on it. I really love the car and don’t want to part with it for any reason just yet. For the last year or so I have been experiencing occasional stalling issues. Generally at cold start up (but not always) and within the first mile or two of travel – all kinds of weather. It is a mechanical stall only – all electronics continue as if nothing is wrong. I have taken the car to several auto repair shops and have had the codes checked at the Dodge dealership to no avail – nobody can really tell me what is going on. With the recent decline in gas prices, I decided to switch from regular lead-free gas to mid-grade and/or premium gas. The stalling problem declined, but did not stop entirely. I am familiar with Sea Foam from the Menards store where I work and decided to give it a try. Much to my surprise and delight the stalling stopped – until I again put regular gas in it again. Any suggestions as to why and/or how I can further improve my engines performance?

Great description John!  Considering the favorable results of using Sea Foam in your Caravan fuel, I’d continue adding every 3,000 miles or so.  Wait until the tank is lower (1/8 or less), then add a can and drive at least 20 miles before adding fuel. This allows for a greater cleaning concentration to work through your Caravan’s injectors and upper engine areas. I’d also start adding half a can of Sea Foam to your crankcase for the last 100 to 300 miles of every oil change interval. Last, be willing to try an can of Sea Foam Spray through the intake to clean intake valves, then see what happens with idle improvement and throttle response. Hope this helps!
