'08 Yukon Denali - trying to stall on cold start

[QUIKAG]

Truck has 61k miles and has been perfect to date. When I do a cold start, it keeps trying to stall on me, but the ECU catches it before it dies and brings the idle back up, then it tries to die again. After driving for a minute or so, everything smooths out and it runs fine.

 

Seems like a dirty MAF or something along those lines. Anyone else had this issue and how did you fix it? Thanks in advance!

I sprayed throttle body cleaner onto the maf and into the throttle body and cleaned my K&N filter. The missing/surging has gone away. Thanks for the zero advice I received. For technical information, this forum has gone to hell for the most part.

Maybe if you would have bumped your post somone might have seen it. Your problem is quite common. There have been several threads recently with your exact problem and answer. It's best if you remove the TB and thoroughly clean the backside of it too. That's where most of the crud is.

 

Be proud that you figured it out on your own.

 

Don't let the screen door hit you on the way out.......
