my lmm truck is about 20 % less powerful than before

can tou guys show and explin how to clean properly the throttle body, map sensor and egr valve

can i do it by myself ?

it would be very appreciated

thanks

kk I just realized there is no tb on a diesel sorry bout that ... ^^

I believe cleaning the egr requires pulling the whole system from the motor. I've heard it is quite a pain. I know if you run some type of water/meth injection it will keep the egr cleaner. I'm sure someone else can shed more light on how to properly clean these things.
