Recently i had a big repair on the whole engine such as, new tension, guide valves, intake valves, 4 broken injectors, rebuilt headblock, headgasket, new chains and belt, new chain guides, oil pan, intake manifold, sensors, water pump, new coils, its wires and spark plugs. But i still feel like the car has no power at all, based on my friends vr6 which is same as mine. This car has 175k atm, i had to do this repair because it happen when my car was over heating and it was leaking (compression) from there i got f***ed with all those parts that were broken as mechanic said.

Any ideas why my car is not supost to push as it should?

 

Sounds like you may want to bring it back where you had it repaired. Good luck.
