Motor has a miss when at idle and in either Park or Neutral. Once I put it in Drive it smoothes out. I do realize after owning 2 L36'* and 2 L67'* that these are not the smoothest idling of motors but it struck me odd it would smooth out once in gear. It almost feels like it'* got a cam in it it misses that bad at times. Any ideas?

do you still have the MAF screen in the car. i noticed mine startd doing the same thing after i took the MAF screen out

Vac leak?

MAF screen still in.....hadn't thought of a vacuum leak...I'll check it out...
