I'm still having problems with acceleration and TCS activating even though there is no wheel spin. I've cleaned and swapped the valves on the bulkhead and that didn't change anything. I've checked all vacuum lines. The closest tech is a few hours away. Any suggestions?

I have noticed that it is worse when the car has sat and just been started. Say in the morning when I start car and pull out driveway, when accelerating it keeps the orange TCS light on and hesitates lots (normal TCS symptoms if the car was actually spinning the tires). If I push the pedal about 3/4 or more, TCS light goes out and deactivates system and it speeds off fine. That is the only light coming on. Thankfully no LHM. Driving down the expressway or passing people I have no problems. If I stop at a lot of red lights it starts acting up and the TCS light comes on and activates the system as I accelerate from the red lights. It makes it seem like a vacuum problem, because as long as the car hasn't set at an idle for a bit it doesn't active the TCS when accelerating.

No other lights are coming on. Again it is an Automatic so would it be the expensive ABS sensors? Thanks for any help.
