Bad misfire will not idle by itself

I picked up a 1986 na rx7 that had not ran in a long time and after sourcing parts I was able to get it started. All emissions have been removed from the car. It will start up just fine but when it comes to idling it will backfire like crazy and the only way it will stay alive is if I give it some throttle. Spark plugs are new, tps is new, bac valve is a used but working part, have tried putting in different eco. It would be appreciated if someone could point me in the right direction of where to start troubleshooting. Or if more information is needed I can provide.

welcome to the board.

is the gas in it old or fresh? what about the gas filter?

you are also likely going to be chasing vacuum leaks.

you'll probably need to get a copy of the FSM: Foxed.ca
