My mechanic replaced the turbocharger and the same problem is still present. The oil light comes on and there is a huge lack in power from a stand still. He claims the oil pump is fine and he is stumped. What else could cause the oil light to come on and it lack acceleration?

 

hmmm well oil light could be a ripped wire that goes kind of on top of the engine, every time you accelerate, the oil pressure light goes on and such, i had that before. HE also could be a total idiot, i recommend going to the guys at Migus Auto Works, they are pretty good and know what they do, all my stuff i did by them. They do free inspection, so wouldn't kill you to see their opinion.

PS: Low acceleration, i have no idea about that brother.

 

check the dipstick of your engine oil level?
