DOSNT LIKE GOING ABOVE 5000RPM
 

JUST HAD A DECAT FITTED ON MY96 WRX AND IT AINT RUNNING RIGHT OVER 5000RPM.IT ISNT THE COIL PACKS AS I HAVE JUST HAD NEW ONES FITTED AND ITS NOT FUEL CUT, I HAVE AN APEXI INDUCTION KIT FITTED IF THATS ANY HELP? ANY IDEAS AS IM ITCHING TO GET IT RIGHT!
THIS SEEMS TO HAVE BEEN COVERD IN OTHER POSTS SO SORRY IF IM BRINGING UP OLD THINGS

CHEERS FOLKS

DID YOU HAVE THE SPARK PLUGS CHANGED AT THE SAME TIME AS THE COIL PACKS?

and why use caps locks....? ;)

What are the symptoms? Do you have a boost gauge - If so what is it reading when you get the problem?
Did the problem only appear after 'specific' modifications were added?
As above - were the plugs changed when the coil packs were replaced?

Cheers

sorry im crap at computers:)

no i dont think they were aparently it could be the lambda senser or the afm?

i have only noticed it since fitting a decat pipe i dont have a boost gauge yet next thing on the list to get

define "not running right"

it will pull up to about 5000rpm then it kinda hesitates and judders like it is missing i guess?

Then it could well be:

spark plugs
Mass airflow sensor
Lamda
