Got a very annoying and persistent B2 code but also the occasional AA code. Its a 2000 so I've read all about the carbon build up issue. I'm just looking for a simple yet cost effective software upgrade that might kill that code and maybe take care of the B2 as well. On the B2 the usual suspect sensors have all been replaced and the cats replaced within 30k....I'm just under 100k now.
I'd really love to put a .45 round through the service engine light grrrrrrr but i think the software upgrade might be more effective and equally rewarding if it boosted HP a little.
