Recently had the timing belt replaced along with repairs to the cylinder head, seals, rings, bearings and water pump all of which are still under warrinty. Have noticed that when the car is accelerating there is a hesitation and lack of power at revs below 3000! The car also lacks power when travelling uphill on the highway. It feels like the engine isn't getting enough fuel!

Check and test the following below:

Oygen Sensor
Catalytic Converter
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
Cap and Rotor

Note:If it doesn't apply,disregard.
