It never occurred to me that the computer programming for my '88 with AIR might be run extra-rich at startup when the AIR pump is actively pushing air into the exhaust manifolds instead of blowing in the air cleaner.
I just assumed that it's going to be a bit rich based on the low coolant temp, without being even more rich because of the AIR.
One of our resident computer-tuning experts could probably answer this definitively. Until then, I'd say that unless there's an actual problem with the AIR system, leave it functional.
My AIR pump died at somewhere over 300,000 miles. I had no indication of problem with the AIR pump when the head gasket popped, but the pump was locked-up when I went to install it on the replacement engine a couple months later. 'Course, I had another AIR pump from another core engine that went on in it's place. There's not much to an AIR pump. I'm sure I could fix my broken one with a couple of bearings; all I have to do is figure out what size they are and get replacements.
