Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Has the check engine light came on and if so has the computer system been scanned to see what fault codes are setting?
Is it possiable you can get it scanned and see if there are any fault codes stored in memory? Most auto parts store will do this for you at no charge. If so, post back with the results and we can work from there.
If it runs good after you shut it down it dose not sound like fuel pressure but lets not rule it out just yet, lets see if there are any stored fault codes first and we can work from there.
