    • Remove the throttle body from the engine. Remove the cover plate by prying up on the edges with a small screwdriver. It is glued down with silicone. Under the cover plate you will see a computer module that is also siliconed in place.

    • Dig the silicone sealer out of the right side to expose the position sensor wire terminals. The terminals are spot welded (yes, WELDED) together to the leads from the computer module. Use small sharp diagonal cutters to separate the terminal leads.

Hey, thanks for the tutorial. I have a 2002 S60 that is surging. Was this fix to resolve similar behavior?

DaveK - Antwort

Surging is usually caused by the engine running too lean. Check for vacuum leaks at the intake manifold, vacuum hoses, brake booster, and anything else that's vacuum powered.

Also try cleaning the throttle blade, especially the edges. Some idle air does go past the throttle blade (normally) and if it gets gunked up, the engine won't be happy.
