Ok I had a big breakthrough last night, the car will stay running on it's own now that I have an air filter in front of the MAF with at least the top half of the OEm airbox installed, I dont have an s13 lower airbox to use at the moment.

So now the issue is "hunting" for idle and the ignition timing not being happy at 20 BTDC, it runs best at 30 BTDC when warmed up to 167 degrees. I need to bleed the coolant system better, but I am definitely seeing a change in ignition timing as the coolant temp sensor warms up which is probably a good thing? idk

I am going to work on it more today
