Shuddering (boost Issues?)

The consult plug is the gray plug located at the bottom of the inside fusebox, behind the little coin tray on right side of the steering column. Resetting using the consult plug only resets any error codes you have. You want to clear the self learn, which unless you have a consult cable and software that can do it, just disconnect positive side off the battery, wait about a minute, or give the brake pedal a few pumps just to help desperse any residule voltage. Then reconnect it.

Okay few other things I've noticed!

My Tyres at the back are actually probably twice as warn than the fronts!

Would swapping them around fix a possible attessa issue?

When the car has been sitting in the sun all morning and I drive it, the issue happens twice as quickly or

sometimes straight away!

The engine is going strong when it happens,

the air intake sortof wooshes in time with the shudders

(probably cos the car is jerking)

Also after changing the sparkers n cleaning the air intakes the idle

is heaps lower! I.e 7-800rpm warm!

(there is a slight inconsistancy in the idle sometimes tho)

[BensDR30]

idle should be around 700rpm warm in D (my ECUTalk shows it between 675-700), so that sounds fine for an 'S'

[Tangles]

my idle is around 600-700

sounds like you need 4 matching tyres............ attessa issue

the attessa is an expensive system to fix once broken, ie $5grand repair

seriously think about flogging off the tyres and getting 4 new matching tyres, Id suggest this would fix the issue

UNLESS the attessa is already f**ked

i dont really have the cash to spend on new tyres atm.

would putting the fronts on the rears fix the issue (if it is the issue) for the time being?

i know i read a thread one time that said that works (i think) ?

I would swap them for sure.

thanks man. i got the fronts swapped with the rears today. and went for a long drive... and the issue is gone..

the problem now is the fronts are now the more worn tyres so they dont handle as well (feels a bit spongey and not as crisp)

i'll buy some new fronts as a christmas / new year present to my stag

BIG thanks to everyone for helping me out (specially scotty and cam, i owe u guys)!!
