99 Protege stalls when first started
 

Hey all, my wife inherited a 99 Protege from her stepdad, it has 104k on it, check engine light was on when we got it and had a lack of power, had it read at autozone, P0106, seems a common cause is the fresh air intake hose which had some rubber tape wrapped around it, probably to fix a leak, so I replaced it with a new one. Also gave it an oil change, new plugs, wires, and pcv valve. The power seems to have come back since the repairs, but when it's started when cold, it'll stall after about 5 or 6 seconds. Starts right up again when the key is turned, and doesn't do it once it warms up, any ideas?

Anyone?
