There's been two or three times when my car has practically stopped after my shifting into a higher gear spiritedly. At first, I thought "man, I suck at this whole manual thing. 18 years down the drain." But after the second time, I suspected DSC. So today I was rounding a corner where I remembered it happening, and I tried to shift in a similar manner and sho 'nuf, it bogged like crazy and the light went on. I had not seen the light the first 2 times, but I was looking specifically at the dash when the car stumbled due to my suspicions. Wow. I didn't really think I was driving so hard that DSC needed to kick in. I thought it would have taken more to make it kick in so hard. Ouch.
At least I know it wasn't me now!
