With the p0102 a MAF cleaning spray is best. Don't touch the wires or sensors...you can spray them just don't touch them. Give it a few minutes to dry & reinstall. Reset code & see what happens. If the code comes back you could have a MAF going bad.

As far as your p0449...read this http://www.tahoeyukonforum.com/forum/showthread.php?t=15741 & http://www.justanswer.com/gm/4ijf7-gmc-yukon-xl-denali-p0449.html
