    Recently I work on my 2003 Nissan Xterra, 3.3 liter, v6 engine. It has fault code p0430, and p0328. A catalytic converter under performance level, and knock sensor fault. So, I replace a new catalytic converter; and also a knock sensor which is “pain in the butt” to get to, it is under the upper intake manifold, I have to remove the fuel rail, then the lower intake. After I replace the knock sensor, I reversely put everything together, car starts momentarily, then stalled. But if you step on the gas pedal, it will keep on running. What is the issue here? Is it the IAC problem (Idle Air Control)? Anyone who can give me some sort of guidance, or pointer to pinpoint this issue? Thanks!
