My 2005 Nissan Altima keeps giving PO302 code. I've changed spark plug, coil and harness connector. Whenever I change something, the problem goes away for about a week or two, then returns. WTF???!!!

could be compression, vacuum leak, which is common on this model, faulty injector or wiring.

the vacuum leak is from the intake manifold gasket.
