November 28, 2003A good 'ol dose of Chevron Techron fuel system cleaner does a good job on mine. It's the only one I use, it deosn't mess with O2 sensors or anything.
November 29, 2003If you use an additive, mix it before a long trip.

December 6, 2003If you go to an oil change place they do fuel injector cleaning. They have a 3 part system. The stuff they pour in the gas tank is a super concentrated cleaner. Then they spray cleaner into the intake and they have another can of stuff they drip into the intake. I had it done on a car I had for work (Taurus) a couple of times and it did a good job.
The best way is to take them out and have them cleaned and balanced. Someplace like this. http://www.injector.com/injectorservice.php I've been thinking about doing this to mine next spring.
