So basically when I first start my truck, it starts fine and then it starts to constantly fluctate between 300 and 1500rpms(it sometimes stalls too) for a good 2 minutes like its being starved for fuel, when it stalls it starts right back up and idles like normal, my air filter is brand new, I've also tried putting some injector cleaner in there which helped a little bit but it still does it. The colder it is, the worse it sputters. After it warms up though it runs fine and strong, any ideas? My truck has just under 200k miles and was meticulously maintained before I got it(I personally know the previous owner).
