FUEL INJECTOR ADJUSTMENTS

I have a 94 Pontiac Sunbird LE that runs rough after warming up. I have had it tuned, but the fuel mix is rich. Can I adjust the fuel injector to correct these issues?

The injector is adjusted by the computer. If it is running rich, it could be a couple things, the temp sensor, O2 sensor. Has the check engine light come on?

Let me know.
