need help i have 96 civic hb i start the car after 4months now the accelaration is going up and down when it get warm still doing same thing can any one tell me what it could be?

 

First places I'd look is for an air leak somewhere around the intake manifold or maybe something is wrong with your Idle Air Control Valve(IACV). Could also be air in the coolant lines.

If it was me, and it's been sitting for 4 months, I'd get it nice and warm and then go floor it up to the speed limit on the highway once or twice just to see if that helps any (although I don't think it will) :shrug: Check the oil level, or just change the oil, first.
