Hi all
I have recently had a problem with my impreza turbo 2000, it is spluttering under boost and running really ritch and using so much fule. I have changed the turbo intake pipe, new coil pack, new ht leads, new MAF sensor but still no different. Does anyone have any idea what could be up.
Many thanks

 

What mods do you have?

 

It's stock as far as I know. But the turbo sounds to be working overtime as well.

 

Plugs gapped correctly?

 

I fitted new plugs in December so I was going to fit new ones tomorrow. What should the gapping be.

 

Pretty sure its 0.6mm for the 2.0 maybe someone else will advise, sounds like something in the ignition has failed although youve chainged leads etc

 

If I change the plugs and that don't change anything don't know what else it could be.

 

Many thanks for your help

 

Fuel pump maybe can't cope maybe? Or Leaking injectors? Most new plugs are already gapped

 

Boost leak? Cause rich running, black smoke, poor performance and cause more effort and noise from the turbo.

 

December I got plugs last.

 

Is the intake pipe fully seated onto turbo?

 

I will have a check tomorrow when I fit new plugs. It keeps throwing a check engine light on the dash.

 

Whats the fault code....??

22 nock sensor.

 

So have you replaced it ??

 

Some said that it wouldn't be that so not changed it. Does the Simptoms sound like it could be the knock sensor

 

The knock sensor fault will cause retarded ignition and hesitant running, however a boost leak would suit your symptoms better.

 

Yip good find overfueling to protect engine as sensors failed

 

Change the bloody knock sensor

 

Make sure new one is at same angle and clean surface

 

Thanks all. I will order a knock sensor tonight. Anyone know how difficult they are to fit

 

Once you've changed it stick your name down here and write a short post about your experience. .....
