ORIGINAL: mjr46 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. |

At night, a spray bottle with a dash of table salt, sprayed over the ignition components, like coil, and wires, will show ignition issues by you seing the sparks.

i tried cylinder balance test cant run cause i have 2 codes for my air injection system

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;)
