Engine Shake at Light Acceleration.

[02cumminspower]

My engine in my truck will shake when I am at a light acceleration. Kind of like it is missing. It doesn't seem to do it when I have the cruise set. Any help would be appreciated.

I also replaced the APPS already.

Does it do it when you are maintaining speed with manual throttle control vs. cruise?

If you use cruise to accelerate, does it do it then also? You mentioned cruise set, just seeing if that is set at a steady speed.

Double check injector lines. I had #6 crack right at the head. Truck would idle fine and drive fine. But, under light acceleration it would lope a little.

It does it while a light acceleration. I never tried to accelerate with the cruise.
And I will check the injection lines.

Is it filling the crankcase with diesel as well? If it is I would suspect connector tubes.

Turn off the adrenaline and see if it still shakes.

The problem makes my truck buck at that 1500 rpm and lower while I'm cruising.

I had a power puck that started to go bad and did the same thing. Ended up taking it off and problem solved.

i am kind of having the same problem but more aggressive than your problem sounds. mine does it the worst at 20 psi. does it with smarty and quad completely removed still.

my truck has 150hp ddp injectors, smarty stacked with quad adrenaline, fass 150hd, 4 inch to 6inch stacks, bhaf. i have already replaced the filters on my fass system too. mine starts right up no problems too. and if i romp on it sometimes it wont skip a beat. other times it gets kind of stuck at 20 psi like its missing then starts going and then starts missing again at 26psi.
