Serious hesitation and jerks below 1500 RPM
So I am not sure exactly what situations cause this problem...it is kind of random. But I will be driving the truck and it will be running perfect...then all of the sudden when I am accelerating below 1500 RPM, the engine bucks and hesitates...kinda reminds me of a feeling that a gas engine gives you when it misses with water in the fuel or something.
The problem never happens when the engine is cold, only once it warms up. As the motor jerks and jives its way past 1500 RPM, everything smooths out.
The jerk is very noticable...and depending on how much throttle you give it while it is doing it, it gets worse (worse with more throttle).
Anyone else having this problem?
