“THERE’S A NOTICEABLE IMPROVEMENT”
“This is my 2003 Honda Civic SI Hatchback with just over 57K miles. I got check engine lights for idle air system and engine over speed condition while driving back from San Francisco to the Central Valley. I figured fuel system buildup was the issue as it’s a 20 year old car. I bought it in Feb 2023 with 49,960 miles and recently drove it to California from Nebraska. After using Sea Foam Motor Treatment, the car has not thrown a code since and there’s a noticeable improvement in horsepower, throttle response and fuel efficiency.”
