The missing bolt? Well as Dean points out, this area isn't pressurized, in fact the opposite. There will be a vacuum in this area, especially when you hit the throttle. The missing bolt could cause extra air to be sucked in. So you have a mass air flow meter upstream of this area telling the ECU that X amount of air is coming in. Down stream, you have a throttle mixing in the right fuel for X amount of air and then you have spark plugs and O2 sensors tell the ECU, wait a minute, something ain't right here. So what does the ECU do?
I won't say that this is your problem, but I will say the stranger things have happened.
Brooks,
