I have a 93 LC. What would be the process to delete the Pair exhaust vacuum. Is it beneficial? And would there be any engine codes that would never leave? Would the EGR valve also be deleted?
I've never deleted the PAIR system. I've had a few truck come through that have had it deleted but I don't know if they have any on going check engine lights. The one's I've seen done were deleted to that the o2 sensors could be moved up to the manifolds and a 95-97 down pipe used. I don't know that there's any other benefit to removing it.
