|
|
My 3.0 TD Trooper Insignia was showing signs of letting fuel into the sump,so I've just had the injector O Rings replaced.
Before the the O Rings were replaced, i was checking things out on the Tech 2, and according to the desired values, it was about half of what it should be right across the range. Say at idle it should be 7, but it only read 3, at 2000 rpm it should be 12, but it read 7, and so on.
After fitting the seals, the fuel delivery figure are still the same. Is there something amiss?
It's running lovely and has loads of power
Id be grateful for any advice.
Thanks
Michael |

Thanks Eithan for looking at my question.
Definetly Fuel.
Not having the Tech 2 at hand, but going by the values (courtesy of Old Mill Motors) that reading( Fuel Delivery) is near the bottom of the page.
I'll not give up my day job as a book keeper. |

that reading is a theoretical figure the ecu comes up with based on the other sensors, there is no fuel pressure sensor on the 3.0l |
