Angry 2003 grand cherokee 2.7 crd

has any one come across this befor i have
codes

p0100
p0340
p1652
p0514
p0403
car drives fine not in limp mode
only issue is sometimes after crusing at a set speed for a distance you hit the throttle and it sort of dont work then it will pick up n go and get abit of black smoke but then clears
also on some ocasions ithe throttle is a bit hesitant to work on pull away
but nothing to bad just like a second maybe less then fine


any help would be great just really anoying me now as i have used 3 solus snap on tools and a launch tool and these dont show any codes
but i do the key cycle and this is what i get


had number 5 injector change a while back
i have look at injectors and there is just the usual dirt and junk round the gave a squart of brake cleaner to clean them off and i have no signs of visible leaks what other way would you sudgest checking then


i have cleaned nearly all the electrical connections out with cleaner and the only 1 that made some sort of differenc was the air flow meter i also took this off and cleaned it with cleaner as the car did get started a thew times with deodernt due to faulty injector and it had scummed up the maf meter after cleaning it the engine light when out and ran ok for a bit but now runs like a turd again
eg hesitant pull off and some smoke and light comes back on but then u can stop it lock it unlock it then the lights off sometimes
thanks for any help
