I've read every thread that the search function registered with the following: TPS, IAC, hesitation...
I have noticed a high rpm, full throttle stumble in the truck. I have no driveability issues, no idle issues, "mostly full throttle" high RPM causes no noticeable problem. It feels like a carb loading up. The truck has no major mods, only a K&N intake.
It ultimately "breaks" through the hesitation, but still feels down on power.
I apologize for how stupid this sounds, but I don't know if the problem just started or not. I haven't done a lot of 100% throttle runs through first and second gear. With the pedal on the floor, as the tach climbs to around 4-4.5k, it feels like the truck falls on it's face, then pulls through it and I shift into second at 5800. I feel some surging under load, but have only continued to pull into 3rd a couple of times.
I have made some full throttle, high RPM runs starting in 3, then 4th, then 5th and didn't notice anything. But I have only put 1k miles on the truck since I bought it. I do know that my truck seemed down on power compared to another members truck, but I attributed that to weight and his few mods. This may not be related at all.
I am not getting any check engine lights, so I wouldn't think misfire, or O2 sensor issues (though the truck should be in open loop while full throttle-right?)
I have never been a fan of the "part-swapping" troubleshooting mentality. But will do what I have to ultimately.
She still burns the tires pretty deep into second when shifting after the stumble, but I want to make sure she's at the top of her game.
Any and all feedback is greatly appreciated!
