im having issues with my honda when starting when its cold. i have to give it gas to start it and keep giving it gas to keep the car from stalling until the car warms up. also, while im holding the gas to keep the car running the idle is jumping up and down. but once it warms up its fine and starts fine.

car is a 94 cx hatch with a GSR swap. mods are intake, exhaust, and chipped ecu.

any insight on what it could be? any help will be appreciated.
