Low Acceleration

i keep getting various code. i doubled check all my vacuum lines and seem to be fine.
P0174 would usually be the 1st one to pop up.

but this time P1151 showed up.

after erasing codes. truck feels to run good for about 5minutes before getting more aggressive on the tractor diesel feel. to ñater come to a rolling stop.

yes. both sides look good, as a matter a fact. the passanger side had a rotted out grommet and it was a pia, to find. so i order online....

i will double check again in the morning. and pay closer attention.


would the intake manifold pay any roll in this?

what i did notice previous owner did some stupid cutting to the box man...

but truck was running fine with that like that..this was something recent. thats why i stopped driving it. thinking it was Misfire due to sludgged (oil) spark plugs. and burnt looking coils.

I cant tell WTF you're doing. The elbow I replaced was right next to engine way in back by firewall, passenger side. I recognize most of those pics you posted and wrong place.

that last pic is right but that's not your vehicle is it?

Check this part out dorman 46051. It is in the back of the intake. You can just use some hose to fix. Seems that this was suggested by some others. It will give a lean code and is common.
