ZD30 CRD Lacking performance and low EGT
A plea to the experts on the forum. I have a 2008 ZD30 CRD Cab Chassis. 3" Exhaust, Blocked EGR, Dawes Valve, max boost set at 18psi, with 100kph around 15.5psi. Full Rail pressure well over 22000psi
The engine runs well enough but lacks performance in 4th and 5th. EGT temp never gets over 320C.
It will run now worries up to 120kph an the flat but the slightest of incline it loses power with low EGT.
I have had the MAF checked, have replaced the MAP sensor as it was throwing a low boost error (reading in vac) no sign of limp mode errors.
I do get the MIL with the associated EGR low flow error due to a full block plate
Seems to me that there is not enough fuel (Limited somehow) showing as low EGT
I don't know what else to check.
What would be the symptoms of a dodgy injector? One not letting full fuel flow through?
TIA
