1997 Volvo 850 Wagon Project

Before injecting Seafoam engine cleaner into the intake manifold, I wanted to clean the throttle body butterfly plate.  To access this you have to remove the throttle pulley cover and main hose from the air cleaner box.

Used ordinary TB spray cleaner for this and washed out as much gummy residue as I could.

Before:

After:

Also removed the idle air control (IAC) valve and sprayed a lot of cleaner in both sides to clear it out.  Maybe engine idle will improve a bit with cleaner air passages.

Seafoam treatment should help further clean the throttle body and IAC valve.

Approx. $4 spray cleaner
