Hesitation again ('90 300SE)
Hesistation is back again.
Occurs mostly at night when car is driven and the weather is cold. My temp gauge at night will not go above 80 unless driven for a good long distance.
During the day, when temps are above 50, hesitation is almost always gone, EXCEPT for when temp gauge is between 40 and~80, as when warming up. During this time there is always a strong stuttering.
Hesitation is same at all speeds.
Car starts instantly, returns 20mpg everytime, burns no oil.
I realize diagnosing a hesitation problem online is a long shot, but any ideas would be great.
