no power pulling out.

[YukonJacks]

I been noticing a lack of power pulling out of the driveway, I can floor it, and I seem to crawl, then after that I'm good, I can jump on it at a stop light and there is no hesitation. Any Ideas. I have about 88k, Plugs and wires were replaced at 85k. I already checked none are loose. Engine oil and diifs are synthetic. Tranny oil and fiolter have been changed also.

Yes, funny thing is I will have driven 12 miles, when I drop my dog off at my folks house, thats when it happens, once I get moving Its ok. Its almost like its getting to much air for proper combustion

Mine just started acting up this morning with something similar.
Really rough idle, almost like its going to stall and poor throttle response????

I have 44,000 on my "03, hav'nt changed plugs etc. yet, might it be time?
