I have a 91 Honda Accord H22 full swap( everything works I.E. A/C, Cruise Control, etc.) But when i get to about 3200-3500 Rpms in the lower gears it sputter/jumps. When Im in fifth gear and hit 60-70 mph it slightly shakes. and when i get to 70mph it also sputters/jumps. Im wondering if this could be a dirty fuel filter or if it's something more serious.(I.E. M.A.P. sensor. M.A.F. sensor.)

Also i just bought it about three days ago and it runs fine other than that. but it has no hose connecting the head to the AEM intake, could it be something as simple as that.

Just new to this and trying to give you guys as much info as possible.
