I've been experiencing rough idling on my 2003 Mitsubishi Galant for the last year or so. It has 182,000 miles on it. About every 6 months now I use seafoam cleaner in the tank and that clears it up temporarily, but then it comes back.
I heard using a pressurized cleaner in a can attached to the fuel rail does a better job, but I'm not sure how to get the hose. I can buy the Pro Cleen can from O'Reillys.
Has anyone tried this? Buying a professional kit is anywhere from $170 USD to over $1000 USD depending on the equipment. It's $100 to $150 USD to have someone do it, but I'd like to do it myself if it's effective.
