Your sig says you have a 1997. You really need the full PXXXX code to best help you. Two digit codes are not as specific as the full codes.
The "key-on, key-off" technique won't give you the full code. Assuming you used this to get the 71.
You can only get the full codes by using a code reader or a scan tool. Some parts stores like Autozone will read them for free.
Get the full code or codes and post them here for comment.
Without data, all you have is an OPINION!
