I have a 1993 240sx, KA24DE. Between 2k-3k RPM's it sputters or hesitates and sometimes I feel like the HP is halved. Also, when I'm just consistently driving on the highway, doing about 60 at 2800 RPM, it sputters for a few seconds, then runs perfect for about a minute, then sputters again, repeat repeat.
I need some ideas on what this could be. Bad injector, bad plugs/wires, bad fuel pump? I don't know.
