I need some help. My 99 GA SE2 does this weird starting thing.....almost every time now, when the motor first cranks over, it's like the motor detonates. I hear and feel a loud clunk, and then the motor idles and runs fine. Also, when accelerating slowly in say 3rd or 4th, it's like the tranny tries to kick down, but isn't sure if it's supposed to, so it causes a jerking or sputtering. I know I have a couple of small vacuum leaks in the upper intake plenum, but don't think that it could be causing the starting issue. Any ideas would be appreciated. I need to get a handle on this, given that it's my only car at the moment. Also, has anyone had any issue with the torque converter taking it's sweet time to lockup on shifting? It's almost like the transmission is slipping, but it's not that severe.
