I have a 03 ram 1500 reg cab with the 4.7 4x4. Every time I start it up cold the trucks coughs when I let off the gas. It only happens the first 5 minutes after a cold start. It only happens when I get on the gas (normal not hard) then let off to stop or something then get back on it. It's like the air fuel ratio is messed up or something. I have no idea. I have a new battery so that is not it. Anybody have any suggestions? Only once has it chocked so hard it cut off on me.
