I replaced my fuel filter and my IAC thinking that would help. I can notice the IAC has made it less frequent to surge than before but it still does it. During this process it will backfire through my air filter box and sometimes through my exhaust. I pulled my throttle body off and cleaned it, as well as the sensors attached that I did not replace. I don't understand what is doing this, I have done process elimination and it just won't work. Any answers or advice?
have the same problem?
