Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, and thank you for using Just Answer! My name is***** me a few moments to review your question and Ill do my best to assist you.
Hello, is the check engine light on? Any warning lights? Any diagnostic trouble codes stored that lead you to replace those parts? his is a 5.4 2 valve or a 5.4 triton 4 valve engine?
O its a 2 valve modular engine, not the 3 valve triton engine. How many miles are on this engine? Is it the original fuel pump?, Fuel pressure is good? It passes Key on engine off and key on engine running tests? No misfires stored in mode 6 data when the mechanic checked using a scan tool?
