Has anyone ever had to replace this thing before? I came across the part on ebay yesterday and bought because it said that if it failed it would cause you rpms to drop whenever your a/c compressor came on. My truck drives lousy when the a/c is on. It feels like the compressor is putting a strain on the engine. Any advice? I bought the part just in case.

This is the screw/bolt for adjusting the A/C compressor idle up and should solve your problem.

Ensure the engine is up to operating temp, turn the A/C on max, adjust idle up for @ 1100 rpm when compressor is on. Normal idle should remain @ 800 rpm (+/- 50 rpm).
