i need help!!!!!!!!!!

whats up guys, just a few questions to see if anyone may know why my car does what it does any way onto the issue. anytime i take my car out and just drive it nice and don't beat on it for some reason when it gets to around 3 to 4k it sputters horribly but if i beat on it and just floor it i don't get that problem. someone told me it may be the injectors but i just wanna see if anyone else may know.
thanks Brad

btw the car is a 90 s13 240sx hatch with a ka24de swap

there is nothing wrong with your car. Its just telling you that it likes to be mashed on at all times. Be happy that you have a car so willing to take a beating. LOL!!!!

On the serious side i would definitely go with ECU or MAF, then injectors. My guess is injectors tho, might have a slightly clogged one. causing incorrect fuel flow at smoother acceleration. Try some injector cleaner and run a tank of gas thru your car. See if that helps.

Buy some Chevron Techron fuel cleaner and some CFC MAF Cleaner. Follow the directions explicitly on the bottle. You can potentially ruin your sensor if you dont. Also check all your intake piping and vaccuum connections for leaks or loose clamps. Sometimes partial vaccuum on partial acceleration will draw in air after the MAF causing a lean condition.
