engine bogging down when coming off throttle - toseland - 23-07-2014
Ok.. symptons..
when you give it the beans, if you let it drop off of the loud juice and fall back to idle itll bog for a split second (like you try to pull away in the wrong gear), chug once or twice, before filling itself back out to a nice smooth idle..
its as if the revs fall a little too far then pick back up again.
Bosch pump
LDA ground (although i am not sure how aggressively)
Gov. modded
no smoke when idling but some on full boost, fiddled with the compensator to reduce this and now it only coals if i mat it out of boost...
other than this it runs sweet as a nutt..
any ideas?

Two issues,
either your pump is emptying due to lack of fuel supply to it, or your anti-stall spring is not setup properly and not kicking in when your idle drops too low.

it will likely be the anti stall spring as i have new 3/8ths fuel pipe throughout...
where be le antistall spring and how to set it up!?
