this might be something to consider, check your MAF sensors for damage. I am not sure where your spray is in relation to the sensors but there could have been some blowback that damaged them causing you to have the random misfire codes. i would also pull the manifold and look for any possible dirt/burnt gas etc it should be clean if it is not then that may signal something blowing back that could have possibly got to the MAF sensors.
