Sounds like the car either has a problem getting fuel, air or spark. mechanics can run diagnostics on it to pinpoint the issue.

Jimmy has problems starting when its cold. the egr code popped can this cause a starting hesitation problem?


Yes the egr valve could cause starting problems. If it is sticking open it would cause a huge vac leak.
I would want to know what the trouble codes are in the computer first. Those codes would help a mechanic nail down the problem area and what to check.

AWD light!


This light is telling you that a problem exists in the AWD system, the light reset's everytime the key is turned off, then because the system fault s still there it comes back on, the 20 second delay is the time required for the system to test itself.
