i have really slow acceleration and can't figure out if its the cat converter or something else. i've replaced the fuel pump and filter thinking it may be this...but no improvement. the car suddenly didnt want to go over 40 km an hour one day and it had excellent emissions last year..does this mean anything?
it has 174,000 km and has also had a tranny flush about ten months ago. the air filter was replaced 3 weeks ago and the brakes are all new so it can't be the calipers.
there's no check engine light on and its underheating, not overheating like cat converters usually show when needing replacement?
