95 D1 resetting check engine codes.

Is there an easy way to dump all the codes? It was run with an error-prone idle air control valve, for a few months so it has stacks of 48s. Any way to dump them all at once? Im going on 2 hrs now of one at a time. And it's getting really old.

I'm not sure how many codes can be cleared all at once....It's my impression they had to be done one at a time.....I pull the "injector" fuse out from the underhood fuse box for about 20 seconds
