G`day all, new to forum, seeking knowledge. I purchased a used, VZ 2004 , L E O alloytec v6 205000ks, did everything fine prior to purchase, had small heater valve leak , no big issue. approximately 900 kms later had misfire at idle, quickly got worse missed at stable revs on highway , cruise enabled. fine under accelleration, for next 100 or so ks,not getting hot using very little coolant, 500 ml in 250ks
then worse , using , 500ml coolant short trip,10kms , pushing all to overflow ,on highway ,if I let it ,[I wouldn`t], on longer trip 150 plus k`s, I never let it overheat, as I was continually checking fluids, I live approx 3 hours from city, & needed to learn if it was reliable enough, it wasnt.
was told about this forum so had a look,
replaced radiator, heater pipe control valve, o2 sensors, checked coils [all fine]
pressure tested cooling system, [Leaking down.]
signs pointed to a head gasket problem ,& slight rattle to timing chains on cold morning start, I decided to have it reconditioned.
done locally due to distance from Perth.
replaced, big ends, gudgeon pins, pistons, & rings, welch plugs, all seals & gaskets , Head bolts, full timing chain & gear set, guides & tensioner`s , water pump, coolant cap, radiator hoses, thermostat
upon completion - engine starts, runs, drives, holds coolant, But still misfires
still no codes are shown , no check engine light on.
read more of forum, then consult holden dealer , common opinion, ecu faulty.
workshop purchase ecu, gain code from holden for old ecu,
snap`on scantool plugged in for removal, code entered, Incorrect code , consult your local holden dealer, workshop consults holden dealer , they say that`s the code,
they are willing to look at it, at hourly rate,
the nearest is about 2 hrs away, & I would not be wise to drive it, so that means a tilt tray, from somewhere else, to here, then there, & return on hourly rate.
Question; If thats the code , why wont it work, & if its incorrect code, why does the car start , run , & drive, with no fault codes, { dtc`s ,is it ? } coming up ? .
also is there another way of finding the code for ecu on scantool, or elsewhere ? as I have read enough to understand , I cant replace the ecu without the right code, & holden say for sure , they supplied the right code. we only get 8 tries, & I think were half way.
sorry its a long thread, but I though the full story may be important.
With thanks in advance for all & any help.
