OK, so this has been a problem with my truck since I bought it. At throttle tip-in, the truck hesitates horribly, then takes off. I can avoid this by giving more initial throttle, but that's not feasible, practical, or safe for a number of driving situations(ie: traffic, parking, etc). I've done a bit of reading on here, but my problem has some conditions that others haven't seemed to have. First and foremost, this problem does not exist when the truck is still in it's cold start cycle. It's only after about 60 seconds or so of run time that it first rears it's ugly head. I'm not getting horrible fuel mileage(around 14mpg, which I feel is pretty decent for 30" tires and my heavy foot), and the truck doesn't seem to be down on power.
I had it in with my mechanic for some other things, and the only thing that he found that he says may be related is a low manifold vacuum reading. The specification range is apparently 15-22", and it's showing 15" exactly. I'm not sure if that is related or what, but I figured I'd mention it. Oh, and before anyone says it, the TPS has been replaced and is adjusted properly.
Any thoughts on this? I'd really like to get this worked out, as it's really taking away from my enjoyment of the truck, which I otherwise love. :helpme:
