inspect ignition components..like cap, rotor , wires and or coil

also check plug gap try gapping at .042" and see if it helps, and if you have platinums... ditch them for stock coppers.

clear the codes and try again if not then you'll need someone with a portable lab scope to look at ignition system patterns to narrow down miss..expecially when all parts are new
