Fix For My Problem (power Loss At 3000 -5000 Rpm).

[Sydney GTS]

Hi guys,

I had a problem where my car was losing power at around 3000 + rpm, at which point it would cough and splutter/ lose power etc.

I finally gave up and took it to the mechanic.

The problem was that the fuel filter was well overdue for a change and a whole heap of crap got through into my injectors.

THE FIX WAS

Fuel Filter changed

Injecters cleaned (make sure they are cleaned "off car" not "on car")

and Fuel pump replaced with aftermarket performance pump.

*** I would like to say thankyou to the guys at NG JAP, they did a great job and i recommend them highly ***

Hope this helps as i have seen many posts with this problem and it is absolutely horrible to drive.

For good measure I had it tuned as they had a dyno and here are my results ... Not bad for a stocky!!
