2003 Accord auto 4 cyl

you have multiple computers - they're just analog, not digital. distributor spark timing mechanism, mixture vs. flow for your carburetor[s] and auto transmission ratio vs. load/speed are all examples.

digital computers are much more reliable than analog - typically 10x more so. so your complaint is really about needing a different set of tools to deal with them. and the potential for abuse when dealers lock you out of your own car by keeping things to themselves as a means of extorting money. fortunately though, with have this "interwebs" thing, and we can get around pretty much any "dealer only" b.s. if we know where to look.

search craigslist for here in kalifornistan. they pop up from time to time. no rust. if it works, just fly out and drive it home.

They also show up on the "This Old Honda" classifieds. Eventually, I'll find the one that will fit my needs.
