Nissan Altima hard to start when cold

Fix Nissan Altima hard to start when cold P0011, P0340

If you own a Nissan Altima with trouble codes P0011 or P0340 that is hard to start, especially when cold, you may have a stretched timing chain. The first step is to check the variable cam phasers since they change cam timing and can cause the codes. But if the cam phasers check out ok, pull the timing covers and check the timing chains. If they’re loose, replace them.
