Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, do you have the exact code number they gave you. It sounds like you are doing everything needed. Eventually you will need to change injector o rings and injector cups. That is the next big thing you will need. Other than that just keep maintaining your vehicle and you shouldn't have any issues.
I forgot to mention I would always flush the cooling system at 30k mile intervals. This will ensure longevity of the engine as well. If you have more questions please let me know. Also please remember to rate my answer so I receive credit for assisting you.
Hello, did you decide to buy the vehicle?
