Belta sputters on cold startup! Any suggestions?

Hello
My car issue is that it hesitates/sputters for several seconds and then it idles normally and runs perfectly fine. Then if I again stop and start the car, it starts fine without sputtering after startup. Only happens after the car is standing for a long period overnight o r say 6-7 hours on a cold startup. I replaced the battery with a good one to check that is the battery is creating problem but the same was happening again. I also changed the spark plugs with new Denso Iridium ones but still facing the issue. I also have scanned and cleaned the Throttle body and MAF sensor and one error code P1605appeared. Any suggestion please.

try mixing some hi-octane fuel, Altho cold starts is normal, this will get worse with time as winters are getting close, I think you also need to re-gap your cars spark plugs.
