Hoping someone can help, I have a 04 Colorado with 150k miles on it. I have had a half dozen instances when I try starting the truck it will either not start or will start and buck and sputter then stall unless I throttle the pedal. I will shut it off and usually on a restart it will be fine...

Hi all, I bought my 2016 GMC Canyon SLE All-Terrain Series earlier this year in April. It had 32,xxx miles on it when I purchased it, and I just crossed over 40k last week. I love the truck so far but have had one glaring issue I hope someone can shed some light on. One of my favorite things...
