SOURCE: need how to find TDC on 4.3 v-6
Remove # 1 plug and stick your finger in the hole, roll the engine over by hand, when you start to feel pressure in the cylinder you are near TDC, just check the crank pulley marks to zero it to TDC mark on pulley.

it really doesnt matter where it points,as long as you plug #1 plug to where the rotor points to,with the crank at top dead center on the timing marks,just to where you know it is.But if its really important to you to have it done like the factory sets it then let me know since i own a Bronco with a 5.8

I suggest you have the injectors tested by the dealer, the sludge buildup will not cause a miss fire. to clean the throttle body use carberator spray while holding the engine idle high.
