rough idle right after startup

[dtholmanmax]

Hey guys - simple question for you - every now and again, if my truck has sat for a day or two without being started (or sometimes randomly) when i start the truck it will idle down/idle rough for a second until it seems to get more fuel. is this related to needing a new fuel filter? runs fine otherwise. truck is an 05 v6 with about 60k on it.

thanks

How's the fuel sytem?

Hey Texas, I hear there's snow around your area too, no?

How's the fuel system? Everything up to date as far as the fuel and air filters?

Using Chevron?

Have you scanned for codes ... just because the SES doesn't light up ... doesn't mean there isn't a code stored in there. Mine did the same thing and I scanned it just for SNG's and found a MAF code .... cleaned the MAF and problem went away.

Idle air control valve

I had rough idle problems about a year ago. with help from this forum it was determined that it was the idle air control valve. a new one costs about 60 bucks, but i just took mine of and sprayed it out with a whole can of carb cleaner. not sure if this is a recommeded approach but i let it dry out for a day put it back on and haven't had a problem since.

It could be the MAF sensor, IAC valve, dirty throttle body, or an out of spec engine coolant temperature sensor.

Are there any write-ups with pictures on how to clean the MAF sensor, IAC valve, and dirty throttle body?
