car stutters at 4500+

[audiomaster1990]

i have a 93 dl, and at about 4500 rpms and after, my car will start to stutter. it doesnt matter what gear im in, and im having no other problems at all. i just installed a new timing belt, injectors, fuel filter, spark plugs/wires, and distributer/cap. if i drive the car like an old person and shift below 4000 it accelerates fine, and driving at a constant speed is no problem.

Any opinions

sounds like fuel cut i had the same problem with vaccum leaks check your hoses and make sure none are cracked or busted
