I put on my new wheels today, and now when I try to take off in 1st gear, it sputters out and dies as if the E-brake is engaged, which it is not. If I take off in reverse, it moves backwards. If I let go of the clutch when the car is *OUT* of gear, the car goes backwards under power.

Before all of this, I simply backed my car up near the garage door and parked it so I could put my new wheels on. No weird noises, not hard going into gear, no grinding or anything. Nothing. Now this.

I do have a new clutch in it, about 300 miles on it. I'm sure this is related.

Anyone?
