Frustrated yet again.... my '94 854T has been acting up lately. It all started with a rough idle in park, but only when the engine was cold. It then progressed to an extremely rough idle in all gears, no matter what temp. Now it wont even drive right. I took it around the block to get the engine warm and the motor wouldnt rev past 2000rpm, no matter how hard I pushed it, it would just shake and try to pull, then "give up". It also seemed to be shifting gears a lot. It is by far the worst in Reverse, and once warm, barely noticeable in Park or Neutral. It starts just fine, but it does need an o2 sensor. Any ideas, please help! Thanks. ~Cody Julian
