occasional miss and backfire

My 93 300e 2.8 occasionally will miss and backfire. When it occurs, granted rarely, it is usually when I stop for a sign or light and then take off right away. The car will stumble, miss, then backfire before taking off. It also happens occasionally when put into reverse upon hot starting. Other info that might be related: The weather is hot right now, codes are present for egr bad and for upshift sensor (both ongoing problems i havent got around to fixing as I have no smogging problems and my cold running seems fine without the car holding a gear forever). The other intermittent problem I get is a surging Idle, most prevalent in reverse. This one has me stymied. Thanks for any advice.
