My 2005 Subaru Impreza 2.0 GX Sport N/A has had a misfire for the last couple of months, it is worse when under load and if you put your foot down it splutters and it very juddery, worse at lower rpm. I have taken it to be looked at by a garage and he plugged his computer and he told me it is the throttle body, and that it needs replacing. I am trying to source one, but i am going by the code on the one currently on (RT60 3-70) but i cant find one either new or used with the same code. Will any throttle body from an EJ20 engine fit and work or does it need to have the same code as the one currently on? I assume my engine is the EJ20 anyway, i am fairly new to subaru's, so if you could also clarify this for me also..
Reg - GK55 XVJ
Model - Impreza 2.0 N/A GX Sport
Problem - Misfire at low RPM, sometimes a very rough idle & worse under load & the more you put your foot down.. Told throttle body at fault
It is a WRX STI REPLICA by the way.
I have included images of the car and code on the TB.
Thanks guys all help/advice/information VERY appreciated
