Ok guys my car is jumping a little between 2-3k on the revs.
On idle it is every so often dropping as if it may stall but never does.
I have replaced the turbo with a td05 16g
I then put a decat up pipe on it and removed the egt sensor- put a resistor in the slot for the egt sensor though
The car was running ok still at this point with no engine mgt light on.
I then put the ngk 7b -one stage colder spark plugs in the car- this is when the issue started.
The car started jumping all over the place and idle was really rough.
Engine mgt light was flashing also at times while driving
I then removed the spark plugs and gapped them all to 0.7mm
Now it seems to be ok apart from between 2-3k on revs where it still jumps a bit.
The flashing engine mgt light has not came back- just a solid light.
DURING THE INSTALL OF THE TURBO I BROKE THE VACUUM TUBES THAT GO TO THE TURBO ACTUATOR AND OTHER SIDE OF THE TURBO.
I am currently using bigger piping without the restrictor pill.
Would this have anything to do with it.
I have been driving off boost since install of turbo.
The actuator line seems wider on the td05 16g than the td04- is this right?
Remap booked in for end of month
Experts and peers please please help!
I will be gratefull for suggrestions to try- thanks!

 

*DURING THE INSTALL OF THE TURBO I BROKE THE VACUUM TUBES THAT GO TO THE TURBO ACTUATOR AND OTHER SIDE OF THE TURBO.

This is the t junction where the ruber pipes meets from each side of the turbo-one has a restricotr pill in it

 

You really need to read the diagnostic trouble code (DTC) associated with the check engine light. Your mapper or a dealer should be able to check the DTCs. Sounds like it's plug or coil pack related given the CEL started when you changed the plugs.

If it was me I would swap the old plugs back in and see if the problem persists.

 

ok- shall try that tomorrow thanks!
would the different diamter vacuum hose and fact theres no pill restrictor in maybe be to blame?

 

Sorted mate!!
Turns out one of the spark plugs i had put in had a crack on it!!
Replaced with old spark plugs and all is good - no light!!
Phew!!
Running ok again as well!!
Cheers for your help

 

PFR7B the same spark plug exactly as BKR7EIX in the NGK IRIDIUM range?

Cheers
