sucky engine
While I was cleaning my garage, I left my X on, since it was only going to take 5 mins..... I noticed that every 5 seconds or so, the RPM's would slightly drop and I would get a "suck" sound (like a cold air intake) Is this normal?? I'm running a Greenfilter, oil level is good....

Car is 2005 4.8is with 16K miles!

is the compressor kicking on and off - the load on the engine is changing therefore it must compensate
