Vectra C, another tale of misfiring injector 3

My recent change of  job to a company nearby, on cycling distance, caused the Vectra to be a lot less used. But that did not hold back for causing more problems. First there was an ice storm (in the f****** middle of the summer!!!) destroying the roof, hood, front left light, and front window, and than 2 days later there was suddenly this problem with injector 3. The actually problem goes like this: the engine sound is different, you hear it doesn’t run like it should, and when you drive the car it shakes and stutters and it has no power at all. Almost like driving a tractor. I took it to the garage for a readout and there they told me “injector 3 problem”. Costs to fix it: approx. € 450 for a new injector not counting the administration costs and loan of the mechanic…

O Deus

Googling around however revealed that the injector problem is actually very common for the Vectra C. Actually, it’s always injector 3 that goes first! The tale goes that because of poor ventilation on injector 3 and the process of it heating up / cooling down causes the connector to not be so tight anymore which on its own turn causes a bad contact with the injector itself. And we all know what happens when you run current through connectors that do not connect so good anymore… Here is a picture that shows you the straight difference between connectors 2 and 3:

As you can see, there is a lot more dirt around connector 3 which is on the right side (always start counting connectors/injectors from left to right). To fix it I removed the pink plastic cover surrounding the electric contacts of the connector and next take a screwdriver and press the contacts at both sides together so that they tighten again around the electric contacts inside the injector plug. Probable a short term solution as the problem will most probable return very soon already, but it’s a one minute job so it is okay to get you back on the road again. On Ebay you can find injector wiring remedy kits nowadays for £ 15, not so bad compared to the € 450+ that my car dealer first told me to pay for installing a new injector (which is not faulty at all).

And this brings me again to the question: why is it so hard to display fault codes on the f****** display of the car? Reading out the car is € 25 for a 2 minute job, smells like easy money…

BIOS bypassing, yet again

Well, not so long ago I had to bypass a BIOS password on a government computer. Some google wizardness quickly revealed a lot of laptops actually have some kind of admin/master password which can reverse engineered or brute forced, any way you want. I already told you about the http://bios-pw.org/ website which could help you for a great deal. If not, maybe Dogbert’s Blog is something for you. He has some nice tools for you to download, including the source code. Great job man!
