“EVEN GOT RID OF MY HIGH-IDLE MISFIRES!”
“I have a 1991 Toyota 4Runner with 180K miles. It had a rough idle and major cold-start issues. I did a full regimen of Sea Foam Motor Treatment (gas and oil) – after that it ran smooth at idle and no issues cold-starting. So far so good. Even got rid of my high-idle misfires!”
