Lack of power
If your problems started from the day that you had the new throttle body installed, yes this may be your problem. I'll give you some checks that you may perform to check if it was installed properly.
1.Make sure that all the hoses were replaced and all hose clamps were tightened up properly, if it leaks air, your air flow sensor wont be able to read the correct air flow into the egine which leads to poor performance.
2. If it is second hand throttle body that was installed, move your throttle shaft where the accelerator cable is attached to, up and down. If there is a lot of movement you will have to replace it or get it re-bushed.
3.On the side of the throttle body is a black unit attached, this is your throttle position sensor. With the egine not running, move the throttle on the throttle body, you should hear a click sound (a micro switch inside this unit opens a circuit), if you do not hear a click sound it has been set up incorrectly. Loosen up the two bolts holding this unit to the throttle body and turn this unit in the opposite direction of the throttle to rev up the engine if it was running, then turn it in the same direction as if you would throttle the engine but do it slowly untill you can hear a click sound. As soon as it clicks hold it and tighten the lock bolts. Now test it and make sure as soon as you would accelerate it clicks, job done for this one.
Generally look for vacuum hoses that might not be connected or secured properly and or electrical connections that might not be in place.
