Hey did you ever have any problems with how the 4runner runs while on the interstate? I've been cruisin it down the interstate and i noticed it on the way home. when i'm drivin about 75 and i have to put a bit of a load on the engine it sputters kinda like a misfire or a fuel cut issue. dont know for sure what it is but its really annoying. wondering if you know anything about it
Check codes for MAP sensor, . . maybe causing the fuel hesitation??
