Hello and Welcome -

My name is XXXXX XXXXX Im happy to help you ..

I suspect that from what you have describe - you have a faulty Ect sensor..or connection to it..

Im assuming you don't have any fault lights on as you drive so you have no fault codes retrieved -

In that case, that then would usually be down to the ECT sensor fault - Vauxhall supply a new sensor - and for some depending on the cars VIN, will supply you a new connector kit for it too - you will need to speak with them for this -as I say, be sure you have the VIN with you.

Its an easy fix to replace the sensor and connector kit if needed -you will see that when you receive it...and then given what you have said, Im sure that will cure this for you.

The ECT sensor is the engine temp sensor for the engine - it works much like the old "choke" on carb fuelled engines - telling the ECU / management computer, the temp of the engine continually - so if that is faulty, and give false, or no info re temp to the Ecu, the engine will run rich and rough - hence your sooty plugs ..etc.

Just as a tip - I would suggest renew the fuel filer as well -- while this wouldn't fit the sooty plugs issue - they do clog quite easily these and cause running issues - so its worth doing that while you are doing.

So thats the way forward on this one now for you.

Kind Rgds, MIKE.
