it seems like when i hit about 5k rpm in 2nd gear, the accelleration stumbles for a second before continuing on.. after a fresh oil change the problem went away - then 5k miles later, it happens again.. change the oil - problem goes away.. doesnt make much sense to me. please let me know if you figure anything out.. thanks!

today I was negotiating a long right sweeper at about half throttle running about 4K rpms, and hit the throttle at the apex and it bogged for a 1/2 second before it accelerated. Did it again a few minutes later, on another right sweeper. I had 3/4 tank of gas, so fuel slosh should not be the problem. THe stealer did just change out the crankshaft sensor though. I wonder if they remappped the ECU? I have noticed a slight engine stumble since I got it back, anybody have this problem after the crankshaft sensor replaced? I bought this car used from the dealer and I'm beginning to wonder if the prior owner had upgraded the software, and the dealer set it back to stock. Any ideas?
