Preventing rough idles and stalling on a Subaru Outback using Sea Foam High Mileage [SOLVED]
Hi. I have a 2008 Subaru Outback LL Bean Edition with a 3.0L 6-cylinder 5-Speed Automatic transmission, 105K miles. I’ve noticed a problem the last couple days where, when sitting at a traffic light, etc., the engine will be idling properly and then the car will suddenly shake a little and feel like it wants to stall. It then recovers and everything is again OK. This happens within a few minutes of the car starting, after sitting for a few hours. I also noticed the car have a difficult time starting, after being shut down for about two hours. I’m wondering if car parts might need to be cleaned (throttle body, etc.), and what specific Sea Foam products might help in this situation? Any advice would be rather appreciated. Thanks.
Great description Bradley. You did not mention any engine codes showing so my first recommendation is to determine if your fuel filter needs replacement, go from there. As far as overcoming rough idle, hesitation or stalls, start adding full cans Sea Foam’s new High Mileage Motor Treatment to your fuel tank when low and drive at least 20 miles before adding fuel. This will offer a higher cleaning concentration to work through your engine’s fuel injectors, helping restore spray patterns. Another product to help with a rough-running engine is to start the habit of Sea Foam Spray upper engine treatments through the throttle body at least twice per year. Sea Foam Spray works to clean harmful residues from intake valves, valve seats, and chamber areas. You can expect favorable results!
