Hello All,

This is my first time here so please let me know if it isn't the right place to ask this question. I did a search but didn't find anything obvious.

On humid days, whether it be summer or winter, my 2000 S70 goes wonkers. The engine starts running rough, the Brake light on the dash comes on, the speedometer & tachometer drops to zero, the odometer shows all dashes, there's no power when accelerating and the engine runs really rich at speed. Pull over, turn off the engine for awhile and everything is ok -- for awhile. No problems when there is no humidity. What should I be looking at?

Any advice will really be appreciated.

 

Sounds like you have a bad ABS module.
