So I went to the grocery store and as I pulled into the parking lot, I pulled it out of gear to coast a bit and it starts idling at about 1500rpm. It stayed like that untill I put it back into gear, drove it around the lot and pulled it back out of gear. The next time around and almost every time after that, it hung at about 1300 then dropped way too slowly down to about 700-800rpm. Then when it gets to the 'normal' idle, it lopes more than it should and every few seconds it gives off this sound as if I quickly tapped the throttle, but the tach is solid.
What kind of things should I check for this? Should I check the vacuum? I'm pretty sure the TB is closing all the way, so a vacuum leak is the only think I could think of. Any suggestions?
