Got one, Crash and Burn arc, just after the cryo-disaster. IM V1 numbers 303 to 305(?). Tony vs. just about everyone, trying to deal with the various messes his company has gotten into. A hacker got into SE's files and published all sorts of secrets even Tony himself didn't know about. In 305, he finds out Stane had built a gamma bomb factory(?) that's still around, and that Hulk knows about it (this was a Smart!Anti-Nuke!Hulk era). So he gets out the Hulkbuster armor and gets ready to fight, only to find out (halfway through the battle) Hulk was fully prepared to talk it out. Thankfully, Big Green is pretty forgiving, and suggests Tony switch to decaf. This arc is also interesting because it features the New Warriors jumping in headfirst and blowing things up willy-nilly, forcing Tony to kick some tail.
