blm's low ?
Hey guys
I just had a scanner hooked up and the blms were at 100 and the os crosscounts around 10-20. other than the evap., and fuel press reg what would cause this? If the fuel press reg is not ruptured and leaking it should be ok right?
any suggestion?
thanks in advance!

A lot of things can cause a "rich" condition like that. Oxygen sensors, a faulty MAF, leaking injectors. Also, you mention the fuel pressure regulator. Just because its not ruptured doesn't mean its function properly. Make sure the regulator is getting vacuum, or else it will cause max fuel pressure all the time which will cause you to run rich.
