2001 Chevrolet Suburban 1500 LS 5.3L Poor Idle Quality, idle drop out
Posted to GM Driveability on 6/29/2005 10 Replies

Hey GM experts,

I've never seen one like this before. This 5.3L will drop idle speed to almost a stall (but never actually stalls) every single time the A/C compressor clutch is about to engage or about to disengage. The drop out only lasts approx 1-2 seconds...
