hello,
I am getting a po307 and a po207 code on my 2000 Durango, 4.7 with 120,000 miles. The car is running bad.
Does anybody know what to do?

 

Might be bad injector/s. P0207 means injector circuit malfunction and P0307 means misfire on cylinder 7. Swap cylinder 7 injector with another and see if it changes code to that cylinder. Also, how are your plugs?

 

Thank you for your reply I am hopefully replacing plugs today with E3 .48 spark plugs and i will also switch the injectors. I will be sure to give you an update. Thank you again.

 

If memory serves me correct, the 4.7L engines are really finicky about spark plugs...they don't like fancy plugs...Champion Copper plugs (.40 gap) are the ones to go to...there are MANY posts on the boards regarding this...hope it helps.

Hello and Happy New Year,
You were correct, it was a bad injector. I replaced it and added the new E3-.48 plugs and I got to tell you they are very good so far. if they are any different than very good I will be sure to let you know.
I wanted to thank you for taking the time to give me some insight into my problem codes. Much appreciated. again, Happy New Year.

 

Glad you got it resolved. Happy new year.
