1990 Integra sputtering at 3000rpm and wont go past 35000

My 16yr old got this car a week ago. I know the timming belt was just replaced or that what he said. He told here it needed a new water pump and it was sitting for a year.
I got the car home, 1/4mile, and looked at it the waterpump seems fine but I cant get the car to run over 3000rpms it sputters like it has a miss at that point when I give it gas. But at an idiel it runs fine.
I hear a high pitch whine on and off that sounds like it is comming from the distributor or shaft but I only have one bolt tight now from playing with the timming. The engine light is also on. At this point I cant tell if it has enough fuell pressure but Im an old school small block person. Thanks for you help.
I have codes 4 and 7 crank and throtel sensers could it be both?
