I have an '09 3.0L v6 auto trans with 184k miles.
I bought it seven years ago, CPO from a Ford dealer at 34K miles and it's the most reliable car I've ever owned.
Can runs well, but just developed an acceleration hesitation:
If I'm cruising, then step on the throttle, at 1700 to 2000 rpm, the engine hesitates. after that it's fine.
It doesn't do it all the time. when I think the issue is gone, it shows up again. then it's hard to replicate the issue.
The air filter is fresh and clean, and I recently cleaned the MAF sensor with the correct spray and replaced the PCV.
It seemed to help a little the issue is still there.
There is no Check Engine Light on and the car is consistently getting great gas mileage and pulls as strong as ever.
What is this?
My guess is it could this be an O2 sensor issue. Even if it's not, I'd love to change them.
Is there a video or photo of the O2 sensors' locations?
Thanks for the compliment but I'm hardly the oracle.
The PCM's do have flash memory for certain fixed settings, e.g., rev limiter, top speed, Things like idle and fuel trim are constantly changing based on input from sensors.
I'm sure eGuru has a better answer.
Duralast Gold has 30% higher cold cranking Amps vs Ford stock battery, and 5yr warranty, vs 3yr on stock.
Had higher buyer ratings than std Durolast or their Platinum on Autozone site. I assume this means better materials or quality control.
Had a battery in my BMW last over 10 years.

I am needing upper control arms again. I don't think this last set lasted as long as the original ones. I'm wondering if there is a difference between the AWD arms and non AWD arms. I have a non AWD with 18" wheels. I'm wondering if the ball joint is offset more or less. I'm also wondering if the bushings are beefier in the AWD arms. I might just have to go compare them at the auto parts store.
