92 RS 305 TBI. Runs Rich, wont pass inspection
Hey everyone. I have a 1992 RS Camaro 305 TBI that I am trying to get inspected and registered. The car runs a little rich and I wanted to know everything I should be looking at in order to get the car to run efficiently enough to pass inspection so that I may be able to get it registered.
I have replaced the following;
plugs
wires
cap and rotor
02 sensor
I have also ran injector cleaner through as well. What else should I be looking at? (MAP Sensor? EGR? ect...)
Thanks for the help!

there's a lot of things that can cause that but some ideas, Mass airflow, Spark plug not gap'd correctly. Does the car have any aftermarket stuff?

You may need to get to the injectors and check them. Fingers crossed the cleaner works but you want to at least check resistances.
