Welcome! My name is XXXXX XXXXX I will do my best to assist you with this problem.
im sorry your having this problem
im sorry for the long wait did you still need help ?
is the reduced engine power displayed ?
is the check engine light on ?
ok and it was not doing this before it was cleaned ?
and the throttle body is plugged in good im assuming ?
when you cleaned it you opened the butter fly manually to clean it out good on the inside of it ?
Ok what has happened if when the butterfly was opened manually it will damage the TAC motor and TPS sensors built into the throttle body
there is no way to fix this other than to replace the throttle body
it is only serviced all as one part I am sorry to say
the cheapest way out is to call a local salvage/junk yard and pick up a used one and install it and do NOT force open the butterfly
the only way to properly open the butter fly's to clean them is with a scan too connected to the truck and the scan tool to have the computer open it up usually the motor built inside the throttle body
