07 Honda Accord in Limp Mode?

So my car doesn't accelerate as normal anymore and jumps/hiccups around 15 mph and then able to make it to 40mph but won't past the speed. It idle fine at a stand still but won't accelerate anymore

Have the exhaust back pressure tested.
Have the timing belt checked to see if it jumped time.
All motors made by Honda have a common problem with the valves getting tight and the valves need adjusting every 60,000 miles.

My 04 and 07 Accords would do that if the computer was tripped by a bad sensor. If memory serves, one time it was the throttle position sensor. It was an inexpensive fix and the computer was reset, problem solved. A scan tool can likely find what to check.
