Hi

I drive a Toyota Hilux Vigo 3.0J single cab. My engine is the 1kd-ftv (3.0 L td ic) and gives lots of power. Recently serviced but the car is reporting abnormal fuel system and is not smooth anymore - vibrates a lot when idling, at high revs the engine is not smooth. I struggle to attain 50 km/hr. My mechanic and the garage is clueless. The turbo makes a sound when key is on, seems there is something running. The sound wasn't bothering me until now - is this normal? The tank was also cleaned.

I'm also looking for the operator's manual and workshop manual for the car.

Thank you
