Rough Start In Cold

[DJ Englewood]

My 2001 yukon denali xl 215720 miles ran fine soon as the outside temperature drop below 10 degrees I had trouble starting it gave me a very rough start it cut off once or twice now I have a check engine light on any ideas

Extremely good chance it's your intake manifold gaskets... Almost 100% positive replacing the gaskets will remedy this issue!

Oh ok can any damage be done ? And what does it cost to fix

Runs lean, unmetered air entering the engine causing it to die out. definitely not a happy motor, try to get it fixed as soon as possible and for the mean time just give it a little extra gas until it's warmed up to keep it from dying out.
Gaskets are around $30 and if you can't do it yourself a shop should charge around $250-300.
Very easy to do yourself so save some cash and just read up online.
