Leaving my battery unhooked for long periods, does computer have to relearn the table
While I have my car disassembled for painting, I have to unhook the battery for long periods of time (no doors on it yet). It seems like every other time I crank it up, it sounds like it runs a tad different. I'm sure I need to drive it to clean it out. I've been repainting it and doing a lot of other things for about a year now. But my question is, when the battery is left unhooked for days or weeks, does the computer have to relearn the fuel tables and other things? Just wondering what exactly happens when you hook that battery up and run it. Last time I ran it, it was popping/backfiring a tad. Thanks!

It takes 10-20 seconds or so to clear the computer. Leaving it off longer does not do anything further. Learned fueling tables are cleared and you start over every time. Idle is usually the most noticeable thing affected. The longer it runs, the more it learns and smooths out.

Its been about 5 months since Ive even taken it around the block. But It only gets cranked and ran/moved maybe 2-3 times a month.
