check your sensors

i have that same problem! it used to be really bad but here are a couple of thigns that helped me.

1. get new plugs and wired if you havn't already
2. make a 4 gague ground form the tranny to the firewall(you can always have more grounds)
3. adjust the tps

i still get teh bogging every once in a while but its not as serious as it was before

sensors getting checked soon. and i cant seem to adujust my TPS. I drive a 87 TII S4, and help with this, and would a ground make alot of difference?

Then get a new TPS.
