High rpm while idle! K12 2010

There was a problem of leakage from the oil seal that led to oil entering the plug housing, and in addition a continuous short was caused to the ECCS fuse , the vehicle was taken to an electrician and mechanic, and after cleaning and replacing the gasket and dealing with the shorts, the vehicle started again, but this time at 1500 rpm and it would not go down, the vehicle drives normally, but after a few minutes of the engine getting warmed, the slip control lights come on and the eps system is off, from there the vehicle simply does not pass 2500 rpm and when pressing full acceleration pedal the rpm jump and just getting crazy, I changed the intake manifold gasket, MAF sensor and cleaned the throttle body, nothing has changed yet, I would love to know if anyone has an idea to solve the problem, thanks in advance!
