What is your question?
I am starting to hate this car.
I replaced the MAF and throttle body on my 07 Mercury Milan 2.3 base model with 127,500 aka #TheBethMobile myself. Prior to changing the MAF and throttle body a wrench light would pop on and kick down my RPMs at startup and made it very hard for my car accelerate and it would very slowly. The wrench light would go away and not come on in warm weather or after pre-heating the car during the winter and restarting it. Once the wrench light would continuously stay on, #TheBethMobile would almost kill out from time to time as well when taking off from stop lights and signs. It would drive completely normal when the wrench light was not on. I hooked it up to a code reader and saw that the MAF and the throttle body were the issues, thus the reason they were replaced. To reset the PCM I disconnected the negative battery cable and let it sit for around 30 minutes.
The wrench light is still on and I am having the same issue without the codes besides P2257 now.
What makes this problem better or worse?
Worse when stuck in stop and go traffic
