What were the actual Codes ? I hope you wrote them down.

The codes do not tell you to "change parts" , rather, they tell you the sensor in question is out of tolerance. This could be, and usually is, due to other factors.

Best way to troubleshoot this is to have the codes scanned again, and, post them.

I am assuming you had a p0171, and, a p0174 code. The codes are displayed in this manner.

See my other thread on these codes. I have done extensive work trying to irradicate them with no luck. Hopefully you can follow my logic and actually resolve your issue.
