I was reading up on Dynomax exhaust systems when i came upon their FAQ page and stumbled upon this
"Hi,
I searched the forum to see if anybody posted this question up yet. So here it is. I just installed a cold air intake for my 2000gt. I noticed after driving it for a half hour the service engine soon light came up. I then disconnected the battery for 10 minutes to reset the computer then reattached it again. Soon after I started driving it the light appeared once more. What can I do to have this light go off? I checked all the plugs and they are all fastened. Does leaving the battery unplugged for longer like an hour do any more use? My car is relatively stock except for a cat back exhaust.
Any help would be greatly appreciated. thanks"

"The addition of a cold air kit flows more air to the intake than the stock sonsors recognize. The added air will trip the sensors because the car thinks it is running too lean. Usually, when the cold air kit is added, the injectors most also be upgraded to balance out the fuel/air mixture. Atleast that is what I've always been told"
I am not real car guy myself but i believe i might have the same problem with mine. Is this stuff true or just a bunch of he said, she said sort of thing. Anybody else notice the same problem on their car, i understand hes talking about a V8 but im sure its gotta be the same for our V6
