It seems like when you reach up to and after 40 mph the car hesitates. We replaced the spark plugs and fuel filter, still no luck. Heard it could be the catalytic converter. How do I check that to make sure?

what brand plugs and wires are you using?

i believe the cat is checked by the temperature of it. i could be wrong but i think i heard somewhere that a clogged cat will be hotter than a free flowing cat.

When I had to replace the cat on my 02 the tell tale sign for me was on hard acceleration the car would bog down and hesitate real bad.
