has anyone ever tried to repair a smoked out ECU?...my '90 plymouth laser turbo wouldn't start one day and smelled of scorched electrical components, replacing the transistors and capacitators is really no big problem but what about the integrated circuit? are these readily available at your local radio shack as well? if not where?, one more question....how do i find out exactly what made it go up in smoke before i replace it ....dont want another one to burn either:bonghitte
