    Recently replaced
    Fuel injectors, PCV valve everything smooth


    but after replacing
    Both CV axle and replaced transmission fluid with 4QT (not sure if this is overfilled)
    However, whenever I accelerate I hear my car having a hard time or asking for more power.
    when we know it's usually quiet, is this normal after CV axles replacement and Transmission Replacement? If not what should I do?

    you fill it until it starts coming back out. you can't really overfill it. make sure the car is level and remove the fill plug. you should be able to feel the fluid with your pinky, just at the bottom of the threads.

    Was there anything that didn't seem right when CV axles were replaced? Perhaps something got damaged? Or one of the two parts was defective?

    Sled, figure anything out??? Similar issues in my 2007, when medium/hard accelerating, I get a vibration/hum from either the inner part of the CVs or my trans after replacing both CVs and new trans fluid. Thanks!

    Yes I did. The cv axle wasn't seated all the way or was moved because of the alignment.

    Have you done an alignment? If not do that.

    Also check your intake manifold and egr valve. It might need a clean up

    Drove my car around a bit more today, the more I drove it the more it improved. I thankfully had an alignment done a few months back after replacing struts, so it is still good. Even though my symptoms have improved, I am still going to take a peak at the CVs to make sure all is good there, probably will check for slop in the inner joints too.

    I have a 2007 (Gen2), so thankfully don't have to worry about EGR. Glad you got your issues sorted!
