Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Are you getting a check engine light?Did you go back and make sure everything is connected?
There really is nothing that should have changed by replacing the water pump. Did you check and make sure the air intake hose is sealing and the MAF (mass air flow) sensor is connected?
I would agree and its even stranger its not setting a fault code. Have you drive it around as best you can and seen if a fault code will set. Sometimes is takes some driving?
Just for the heck of it why dont you disconnect the negative battery cable and then take some carb cleaner and a soft cloth and give the throttle body a good cleaning and while you in there also take some MAF cleaner and give the MAF a good cleaning and see if it changes the way the engine performs.
