It could be any number of things as you don't give much to go on. Does the turbo wind up? Is the CEL on?

It bumps forward when I change gear for a little boost sometimes a ticking from engine can hear it inside and a funny mechanical smell there are 2 injectors that are black, asking here for anything I can do for a temp fix as I'm pretty busy with work with no days off so I have to drive it

And no cel isn't on in had a local mechanic I know have a look he also pit a device on in the car and it come up something like no problems


If you have a boost gauge what does it show under full throttle acceleration?


When was the last time the fuel filter was changed?

I brought it about 4 months ago so thought I didn't have to have it looked at! Im now getting black dust from the exhaust coming out 2 injector seats are also black and I'm thinking it could be fuel filter too I will take some pictures soon
