A/F guage is all over the place

[Eliteracingghmi]

I set up the emissions system according to the "race only" setup on the taboo speed shop's website and my A/F guage is all over the place. It starts out really lean, then moves to stoich., and after about 7-10 minutes of driving, it moves to rich. I also am having a problem with my car starting. Could the ignition be playing into this as well?

Changing the vacuum lines shouldn't effect A/F ratio, unless you messed up an important line like the FPR source.

Could be an O2 sensor dying.

could be an imposible to read blinking christmas tree gage

Christmas tree guage is about the best way to describe it. The fuel pressure solenoid doesn't have the vacuum lines hooked up anymore. Think that might be it?
