Codes P0404,P0300,P0308 and P2323

Question

My truck hesitates sometimes when I try to accelerate and sputters  I changed the coil packs about 6 months ago as well as plugs . Any help is greatly appreciated

Answer 1

P0404 EGR potion sensor performance

P0300 random misfire

P0308 misfire cylinder 8

P2323 IGNITION COIL 8 secondary circuit insufficient ionization

Did this recently over heat? What you can do is swap out the coil with another cylinder and retest from there, if the misfire continue the best route would be to rule out a mechanical problem, doing a leak down test of cylinder 8 this type of engine over heats easily and in turn takes out cylinder 8
