It could be part of the vacuum circuit that purges gasoline fumes from the fuel tank.
Tracking. The wheels may need to be re-aligned. 'Tracking' can be done at a garage. They will re-align the wheels so that they are precisely in the correct position for proper steering.
It may be that your steering as also at fault. But get your tracking checked first.
If all you did was have the tires rotated and it pulls now it is probably what they call a radial pull, this is when the steel belts in your tire shift and cause oe tire to grip the road differently causing a pull to one side or the other. Have the garage swap the front tires side to side and if this is the case it will pull the other way i that case you need two new tires if the vehicle is 2wd or 4 if it is 4wd and the rears have more than 4/32" tread wear. It is most likely not an alignment issue.
As far as I know, any child under the age of 12 should not ride in the front seat. Especially if you have a passenger air bag.
