Year of Manufacture *: 2007
Engine Size and Code *: 1900 Z19DT
( Optional ) Scanner Used: VAUX COM
( Optional) Fault Codes: P2279
Had this one towed in to me and it want rev up .
fault code P2279 air take air leak.
Checked all air hoses/vacuum hoses. Looked in live data and every thing looks fine including maf only thing is throttle body staying on 0%. Tested throttle body, tested egr. Cleaned and tested turbo including actuator. Removed front pipe to dpf and it reved so cleaned dpf with kent dpf cleaner refitted and set zeros in ecu, test drove and still not much power But better, removed egr exhaust pipe going into inlet and it runs fine.
Cleaned egr and tested with Vaux com and scoped duty cycle and power and its working fine. Only thing I noticed is the engine seems very smoking/blue smoke like over fueling.
Tested injector leak offs and they seem in tolerance, looked at correction factors in live data and I have 1/215 mg/stroke 2/115 mg/stroke 3/-015 mg/stroke 4/-025 mg/stroke all at idle.
I have removed injectors and sent for tested.
Any advice please.
