I've had my truck for about 2 months now, and I havent had any problems with it, but i've noticed something about the idle. If you hold the shifter **** (manual trans) when its idleing, you can feel a vibration in it, and is kinda an on and off vibration, kinda like if you were to let out on clutch just a little while holding the brake where it couldn't move, and then pushing the clutch back in and doing it over and over. It isn't the slave cylinder b/c it will go into any gear with ease while sitting still. Also, if you mash the gas real fast while in neutral idling, when the RPMs come back down, it will drop below normal idle rpms before it picks back up to normal rpms (kinda like it wants to stall). My truck has 139k miles on it, so im not sure what has and has not been replaced. It runs fine other than that.
