is it my oil pump ?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your oil light comes on at idle and goes off as you rev the engine, it’s a classic sign of low oil pressure. The culprit could be the oil pump starting to wear out, but it’s also worth checking the oil level and making sure you’re not running low. A clogged oil filter or worn engine bearings could also cause low oil pressure at idle. You’ll want to get the pressure tested with a gauge to see what’s going on before assuming the pump is the problem.
