Can I use parts off of a 2001 sunfire pontiac on a 99? Specifically the 02 sensor, trunk lid, and starter. Also I am having many other problems recently, I have a very rough idle and it has been stalling. Especially when put in reverse or at speeds under 20 km/hour. There is also what sounds to be a backfire coming from the area around the drivers feet. I am almost positive its my intake manifold but was hoping for some guidance to be certain. And would I be able to trade the 2001 manifold for mine?

These cars had a problems with the coil housing, if you have not replaced it this is where I would start, this problem will not make the PCM store a trouble code. This guide can help you find out why the engine is stalling
