At idle my altima engine shakes a little rough, but it runs without any roughness or missing. It does not even mis at idle just the roughness. There is no check engine lights on and I have put a scan tool on car and it has no codes. The car has had new plugs installed(the ng v power plugs) new spark plug wires, air filter, maf sensor, another fuel rail with fuel injectors. I have sprayed carb cleaner all around vacum hoses and intake manifold to see if engine changes idle to see if there was a leak and the idle did not change. What do I do next to correct this problem.
