Get hooked into a scanner, check the 02 sensor it sounds as if you may not have gotten the intake to seal, you can use either or carb cleaner to spray the intake and watch the sensor change when you find it, also check for hoses you may have cracked during the repair. I hope this helps.

    Idle is very rough. If you blow it out carbon pours out of the exhaust. But it starts idling rough again.
