ok peoples...
this bad fuel economy is getting anoying again... had it for a while now.. 250km if im lucky
I can drive on the highway or in the city for the same amount of time and ill still get in the 200's
- the o2 sensor is fine i believe, it reports readings between 0-1v according to the pfc.
- the afrs have been checked on a dyno and are aparantly fine..
- never any black smoke or anything
- i've changed fuel filter a few times.
- tried that injector cleaner you get from the petrol station a few times.
- the afm seems fine i dont realy have any wierd idle or missing or anything problems..
- got new tyres recently so it cant be that anymore
- changed all the other stuff, spark plugs etc during servicing..
- driven up and down the road a few times trying to see if petrol was dripping out anywhere.. so doesnt
seem to be leaking..
- doesnt seem slow or wierd or anything
- the engine was rebuilt 500km ago with stock internals but i dunno if that would make the econemy slightly better ?
also because it was recently rebuilt im driving slower so if anything i should be getting better fuel eco now, but grr im not
oh yeah the closed loop thing on the pfc is enabled and when im cruising round at like 60km the inj duty cycle is like 4-7% which isnt to bad ya ???
anyone got any other ideas on what to check ??
thanks
