1997 sl600 issues

My 1997 sl600 has engine code p0507, engine fluctuating between 800 to 1100 rpms, throttle bodies have vacuum, they are turning on and cleaned them, sprayed vacuum lines with water, no leaks. I can't seem to locate a IAC valve, any help would be appreciated

Also my roll bar and convertible top switches are on, roll bar is up and hard top is on. I reset the windows & roll bar, checked the pumps and fuses, don't, know what else to look at, thinking the convertible top module is bad, does that control the roll bar too!!!

You need a new throttle body,spraying the BS spry will not work in this case.
