Would an improper terminal connection to battery cause a p0300? ---

@Yosemite Still a P0300 code. I look at the monitors and everything was ready besides Catalyst, evaporation system, and oxygen sensor. Opened up the hood to see if I could hear any hisses for leaks and I cant even tell, its way too loud. I did hear something similar to hiss though. 1100 rpm on idle [Previous page](https://community.cartalk.com/t/2000-toyota-corolla-wont-start/86221.md?page=1)
