Hi all got a problem, engine is fine on tickover and pulls like a train but when standing if u press the throtle peddel down to about 1/4 and hold it there it continues to pulse or surge up and down any ideas??????
Thanks Carl
id put on diagnostics read fault codes and look at live data ,could be poor throttle pot if in the same position on throttle when fault occurs ,could be a good few things ,
Throttle pot?
I have changed a number of parts that include.
Inj harness
Tryed another ecu
Intank fuel pump
Mas senser
Filter head and filter
Inj seals and washers
Fuel block
Now on changing cam as it has wear on 1 of the lobes that charges the injector.
Other than that i'm what you call stumped
