90_integra

So, this just kinda started happening. I have a 1990 da integra with a jdm b16a ob0 swap. When the motor is cold, most of the time when you start the car it fire's right up, check engine light pop's on and car die's. Turn off the key and try it again and same thing. Numorous time's this will happen. After you start it sometime's you can hold the pedal down around 4k rpm's and it will stay running if you hold it there. If you lower the rpm's under 3500 or so same thing, check engine light pop's and die's instantly. Car doesn't really high idle when it's cold either if you can get it to stay running. after it warm's up a bit it work's fine. No issue's. Could this be a bad tps? Any one have any suggestion's or insight on the situation? Has a new alternator, dizzy and battery. Has a fresh tune up and gas. Just recently started happening. Doesn't matter day or night if the engine is cold it happen's. Help a nub out please, and thank's.
