My 03 ram 1500 with a 4.7L is having a rough start up. I changed the battery out, but when its sits overnight in the morning the truck barelly cranks up or it coughs on the crank up. Then the first 5 minutes of driving it coughs and sometimes shuts off when I slow down for a stop sign. It's like it is running lean or something. I cleaned the throttle body and MAF. Still the same. I was thinking maybe the starter could be going out, but that doesn't explain the choke out and running hard the first few minutes after cranking up.

Any tips or anything else that you would look at?

 

Is the check engine light illuminated?

Edit - I should say, was the light illuminated, since changing the battery would reset any codes.

 

It came on for a small evap leak, but it just needed a need gas cap.
