ps , black smoke is not conductive for high rail pressure ...is the opposite , high pressure heat the fuel and increase spray and burn well and do less smoke , but you do not obtain more fuel like a chip module on the rail sensor ...is different logic , black smoke is your egr and or your intake .....inlet or outlet cac or the intercooler ...or the egr that leak turbo pressure or you do something wrong in the ecu
Hi all, after a short pause i am back
Yeti i know, i did not mean black smoke like you know from low pressure IDI /TDI diesels. It was only a light "puff"
But that is not important at this moment. I still have P0093. I have replaced one of the 2 remanufactured injectors with brand new one. It had higher correction values and i suspected that one to have a leak into backline (waste or whatewer is it called in english). So i replaced that one, but no change.
I try to summarize it again, maybe someone has an idea.
The car starts withou any problems - hot or cold max on 2-3 crank turns.
Has plenty of power, no lack or hesitation or whatever.
If you floor it, you can do that up to the empty tank and it runs without any problem no matter what gear you are in.
But accelerate it to approx. 120-140 km/h, then let it cruise down to 60-80 (below 2000 rpm) with a light foot on the gas and then moderately accelerate again.If you play with it like that you get P0093 quite easily and it goes to limp in mode. That is the only error.
But if you downshift and floor it, it will go like a hell without any DTC
So far:
replaced cracked EGR pipe
new filter head and new filter
in-tank lift pump
new injectors (3 are brand new, one is remanufatured)
overhauled CP3 pump, new MProp valve, new overflow valve....
fuel rail and regulator swapped from another libby, so 2 tested an both seem to be OK (at least in another car)
installed a piece of clear tubing to observe air bubbles - nothing there
Tryed to delete the P0093 DTC from the ECU, no luck. I do not have dtc set, bu it goes to limp-in mode anyway.
Tryed to modify fuel maps (thanks to Yeti) , but without luck either.
There MUST BE SOMETHING in that fu..ing fuel system. But i do not know what. I start to be frustrated from the whole
thing and i do not want to throw more time and funds into that piece of crap anymore.
any ideas anybody?
thx
