Rebuilt an 2003 Mitsubishi Outlander engine.
Got the engine re installed and having issues when I start the car up it will not hold an idle if I take my foot of the gas it stalls out.

1. Battery was a bit low recharged it it test fine.
2. the start work great I can get the engine to start
3. after a few seconds I need to have my foot on the gas or the engine stalls out.
4. the service engine light cam on and I was able to pull the following three codes:
error codes P0349, P0335 & P0715

Suggestion the car not drivable as it is stalls out when ever I have to stop at a light or stop sign.

any insight would be most helpful.
Thanks Don
