Stupid 3.1L (3100)

Any one got a 3.1L "M" (3100) that hesitates when the engine is cold? after is gets warmed up it goes away. its getting real old The car does not use any oil and does not seem to use any antifreeze.

Iac ???

Try using 93 Octane from Shell. My 3.1 did the same until I fueled up with the expensive stuff.
