new project 95 z28 m6...
How did you determine it's running rich? You will usually get a puff of black smoke when you mash it if it's rich. You should also be checking O2 operation and LTFT's in a scanner to verify. Excessively rich conditions will eventually throw a code and light the SEL. A quick check of the vacuum hose at the FPR is a good idea to be sure fuel isn't leaking past the FPR diaphragm and into the vacuum line.
