Hi guys.

why is my 95 wrx using so much fuel, i have noticed the CHECK ENGINE light is now on.

i am also wondering where the diagnostic plug is on this model, if there is one.

Thanks guys beeywrx.

 

2 plug's under the steering wheel mate..right down with the pedals ..as you look up you'll see them...there's a procedure on this properly in the gen tech bit i think.

 

I'm gonna have a guess and say lambda sensor, let us know when you find the code out!

 

Thanx guys, al give it a go and let u know the codes when i get it plug'd in.

You dont need to plug it in to anything, you just need to connect the black plugs under the dash at your feet in the drivers side, connect theses and count the flashes the chech light gives and that will tell you the code.. ie 2 long and 3 short = 23, just post up what code it puts up and we will be able to narrow down the sensor thats failed/ing...

 

Thanx jamz_ seems to have everything on it very helpfull
Much appreciated cheers

 

Cheers f4la k

 

Rite guys plugd the cables in and read the code via the CHECK ENGINE light and its reading 23 and 24 any clue would be a great help

Cheers beeywrx

23.Mass Air Flow Sensor Circuit
24.Idle Control System Malfunction

but remember code 23 could be causing it to have code 24 or vise versa

 

I would say maf over idle control... maf's are the impreza's weak leg

 

Clean the idle control valve first, its your cheapest option, if that doesnt fix it then your looking at a few hundred quid for a maf sensor, if its not the maf then its more than a few hundred quid for a new icv, your best bet is a speciallist to diagnose your cars issue or you could be seriously out of pocket cash wise.

Cheers guys al try clean it then recheck it again

 

Rite guys cleaned the MAF and put back together still just the same, so any idea if there is a subaru dismanteler in edinburgh area, none of the local scrap yard have any impreza's in there yards, or if anyone has a one lying around we could come to some arrangement.
