Hi All
For the first time in 23 years my beloved turbo is suffering running issues
What has happened
What function does this damper perform ? and would it cause rough running and overfuelling ?
I am going to do a fuel pressure test hopefully this eve but is there any point if the fuel damper is faulty ?
Could this be caused by an injector that is stuck open ?
My car is an 87 turbo and is completely standard !
Any help would be greatly appreciated as Id really like to learn a bit if I can ! [

Thanks in Advance

What has happened
- The fuel pump started to fail so this was replaced
- After the replacement she didn't run great but I put this down to a low fuel level
- Put about 10 litres in and she went worse coming to a stop on our driveway (lucky)
- Fuel pump ran without issue - DME relay checked and verified
- Reference and RPM sensors replaced as one had got a clip previously - Set up
- Car fired up but was running rough with clouds of black smoke from the exhaust
- Checked AFM for a stuck flap OK
- Checked the air temp sensor resistance and got around 3kohm which is within range
- Checked the ECU engine temp sensor and got around 3kohm again within range
- Pulled the vacuum hose from the fuel pressure regulator at the back - No smell of fuel
- Pulled the vacuum hose from the fuel damper at the front and there was a drop of fuel and it smelled of fuel
