Alright I have a 91 Integra with a turbo ls vtec and I runs good until I get on it and I starts to build boost then the check engine light comes on and then When I come to a stop the car doesn't idle.

If any one knows anything please lmk

What Map Sensor are you using. You Map is probably picking up the boost pressure, then the ECM thinks something is wrong, so it goes into backup mode, until you restart the car. Just a thought.
