Hello
I have some issues with my 3vze motor truck, while driving I feel like the engine is lacking power but at the same time it sounds like i am driving an airplane. Do you think it is a bad fan cooling clutch problem!!

 

Fan clutch won't effect performance, but could make you run hot.

 

Head gasket leak?

 

Damage to air intake system including the silencer box? Would create a vacuum leak which results in loss of power.

 

It went through the air intake system and noticed nothing there. There is no air leak there.
