As I was backing out of my driveway today, my car bucked quite a bit in reverse. Once I back out, 1st goes smooth, no bucking, and I continue on my way but the engine lacks it's usual punch. As i'm cruising down the road I pull the car out of gear as i'm coming to a stop and it stalls! Fires right back up, idles really low at the next light. Slowly works it's way up to the usual 700-800 but it's real lumpy. I limp it to work, literally cruising into my parking spot stalled out. I think I blew a vacuum line, but I won't be off work for hours. I'd suspect my IAC but the engine lacks power and the TPS is brand spankin' new. Just looking for anything else to check before I get off and make my scans.
