misfire backfire problem solved
went threw all the first causes of this problem coils/plugs/MAF ext next thing on my mind was cats internal fuel filter malfunctioning o2's kept checking stuff and then checked the pcv and vacuum system.... ran seafoam through the vacuum system problem solved will be replacing the vacuum lines soon cant believe it was that simple but that seems to be how it always works out! so advice to people possibly having the same problem check your vacuum system or just run seafoam through it!
