After many hours of diagnostics, it has come about that a shop recommend that I replace my ECM. After much research, I am having a heck of a time actually finding the correct part (except from the dealer). It is 37820-p75-a05 obd2. Are there any other parts I can use that will work in my car? Does anyone have any recommendations as to where I might find the correct part or a reliable R&R service? She is an 00 Integ, LS, 1.8 dohc Non-Vtec. I'm a noob so forgive me if I am asking the obvious.
