Throttle Body Spacer and a ?
I was wondering if the throttle body spacers actually work? Will this along with a cleaning add a couple hp or mpg?
On a side question, my car engine does a rumbling sound at about 1200rpm then stops once it goes higher, my mechanic told me that the mounts seem fine, do you guys have any idea of what it could be?
All input is appreciated!!

A throttle body airfoil is about the only thing that can be added to improve airflow on the stock TB (other than CAI or high-flow elbow)...they are cheap ($30-50), but only worth 2-3 HP if that. Coolant bypass mod on the TB is worth it however. Get a cold air intake if you want noticeable power and mileage improvements if you don't have one already.
