Discussion
Hi guys, I used the launch control and since then the car has been playing up.
First of all it was idiling really bad where he engine wanted to come out the bay.
It was also doing a juddering/kangarooing between 3-4K rpm.
The next day the idiling went back to normal but still judders/kangarooing.
It got scanned in the day it happened no faults came up.
Injector quality is in it limits
No boost leak has been found
Vacuum pressure it sound
Fuel filter been changed
Boost control valve been changed
Maf is new
Turbo spools Nicely and does pick up well even with the judder/kangarooing
No oil leaks
The mechanic had it all day today checking all this and his out of options on what it could be could anyone have any suggestions or had the same or simuilar problem thanks.
