Are there any problems with the throttle body boot leaking. How do you remove the boot. I hear avacuum noise around the boot. When I spray break clean around the boot the idle goes up. Rpm surges in park and drive

Yes, that boot is known to split. You should possibly have a check engine light with p0171, and p0174 banks 1 and 2 lean. To change it, you remove the three 10mm bolts that secure the throttle body, remove the fuel rail, and then the intake bolts. Undo the clamp for the boot and change it. Don't tighten the clamp until you have the three 10mm bolts back in, in lines up easier.
