I just wanted to say that I have a 96 camaro obd2 I would think and I completely removed the air pump and air tubes and I disabled the egr by plugging the vac feed to the egr on the intake manifold.
I have seen no check engine lights in a few weeks of driving.I haven't checked my powerscan hpp or autotap and might have codes in the ecm but they aren't setting the check engine light.Is this strange or what.I assume I have the proper ecm as my hypertech and powerscan work on it fine.
