Actually sounds normal. The oil pump is driven by the camshaft. When at idle the oil pump is pumping slower because the engine RPMs are lower. When you accelerate the engine speeds up and so does the oil pump. So your oil pressure increases. Also the oil pressure will be higher when the engine is cold because the oil is thicker. Hope that helps! Jim
