Was wondering if anyone new if there was a re coding procedure when replacing fuel injectors, I have suspicions one or more is going bad and I might as well change them all if I have too pull them all out in the first place.

 

You might try finding someone local that services fuel injectors. They could be clogged or dirty. How many miles on the car? I work with a local guy here in Denver that tests, cleans, sprays, and replaces orings and provides before/after reports for about $60-$80 for the set. I'd try that route before throwing expensive parts at it. What makes you think they are going bad?
