Leaving aside the issues I have with fuel/air mixture (rough idle), it appears to be worst under load (in Drive), say at a traffic light stop. Idle drops to 500rpm or less, and the engine seems very strained. If I slip the transmission into Neutral, it is much better; idle rpm is then ~650-700.

Is there an adjustment on the transmission to cure this, so the vehicle doesn't feel so strained at idle? Or shouldn't I worry about it?
