2001 Chrysler Sebring engine sputters and stalls in startup

Hi, I just took off the intake cover and the throttle plate and cleaned 'em up. After geting everything back up and cheking that all sensor conectors like TPS, AIR FLOW SENSOR, and all the others where ok I try to start the engine back again but I had to try it like three times to make it run, seems like no gas was flowing or a bad air/gas mixture issue cause it stalls, but after it runs and heats works fine, but the next morning once again I had to start the engine three times before it runs normally.
no codes though. No shaking when iddle, nothing just have this problen when cold starting.
