What do you think?

Well I just fixed the P0420 code by changing the o2 sensors and passed inspection today.

Also decided to change my oile and filter.

Driving her around I noticed it felt like a bit of resistance when I initially accelerate. Almost like a hesitation but she feels fine after I get some speed.
(Not the emerg brake either)

Do you think this is a symptom of a dirty throttle body or maf sensor?

Thanks for any feedback!

Definitely wouldn't hurt to clean the throttle body. I would also check out your air filter too. That can also give a similar feeling.

If you didn't disconnect the battery (to reset the computer) after replacing the O2 sensors, do so. It will take a little driving for the computer to learn again.

How is your oil level? Too much oil can cause the engine to feel sluggish.

Will def look to clean the throttle body.

I did disconnect the batttery before installing the o2 sensor.

And I bought the 5.1 qt jug and used that to fill so think that is the right amount for an oil change?
