Hi Everyone,
I really hope someone can help me with this, The car has been to 6 different mechanics (Ultratune,NRG,Vince Rigoli,JEM,Chester Hill Auto and Subaru Mcgrath) including Subaru Mcgrath and no one seems to be able to resolve the issue.
The issues started shortly after 75000 kms and the car now has 82000. It's a 2004 Subaru Liberty GT MY05 Manual.
The issue is car shudders/stumbles at idle especially when warmed up and when the revs are kept at around 1500rpm the whole car shakes. Normal/on boost driving seems fine, the car pulls like a train.
I am very frustrated with it and at a point I want to actually get rid of it.
The mods on the car:
Phat Dump Pipe
Xforce Catback
with Standard mufflers
Matt (Kido) Tune
Car makes 169kw at all fours (JEM Dyno)
So far This is what has been done on the car:
Front O2 sensor replaced (with an updated OEM one)
Rear O2 sensor replaced (with OEM one)
MAF Sensor replaced (with OEM one)
MAP Sensor replaced (with OEM one)
Injectors pulled out inspected/cleaned/flow tested and put back in the car
