so I have a 2002 kia spectra that had a bad radiator so I had it replaced by a mechanic, when I got the car back I started getting codes for cylinder 2 misfire, and for bad temp sensor. I replaced the sensor and put new valve cover gasket and seals with new ngk plugs. However now its overheating and the engine cooling fan is not coming on, and im getting a code still for cylinder 2 misfire and p0117. any ideas?
