Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

You need to check for a trouble code, Kragen auto does this for free. Also check for vacuum leaks at the intake manifold.

First off I would strongly recommend you purchase a haynes or equivalent service manual. There are 2 indentations on the cam gears. There is an arrow on the oil pump (lower right) sprocket. There is a small dimple indentation on the crank pulley sprocket. The crank pulley dowel pin faces up. Actually, vfaq.com lol
