Next time you want a FI cleaning try this...

Every 6 months I get a 1 pint bottle of rubbing alcohol with the HIGHEST percent isopropyl. Some will say 91% but I found that Wal-Mart has 97%. that means it's only 3% water, and since injector cleaner is 99% alcohol then why spend $2-3 on that when you can spend $0.95 on alcohol.

Add the alcohol to a half tank of gas and then fill it up. Then run the tank almost empty and fill it up again. That will help run the alcohol through the system and clean the injectors.

I have been doing this for about 3 years and have no problems.
