someone please help:

i pulled away in my wrx sti8 uk spec today and it felt a little lumpy, so i tried to put a small amount of boost through the turbo, when it held back (almost like it had hit the fuel defence cut off kind of feeling) and the engine management light came on. it now feels very weak power wise however idles fine. luckily id only driven it a couple of hundred yards and got it home through fear of damaging something further. any ideas?

apart from backbox, ssqv and air filter it is completely standard.

any help will be greatfully recieved

a little update, it does NOT idle fine and doesnt hold revs in neutral. car switched off now as to not do any damage

all fluid levels etc checked and all fine

sorry im a technical dunce

 

Maybe a coil pack.
Same symptoms as mine when coil pack 3 failed.
Called aa and they plugged code scanner in.
Get the ecu fault read and it will tell you.

 

As above, You need someone to read the CEL code

cheers guys, AA already winging there merry way here..... lets hope its nothing serious

 

Post up the code as it's read out..........lets see who wins, Scoobynet or the AA man

Coil pack two failure, any advances on this

 

depends how much of a deep depression im slumped into if told its going to cost a fair whack!! bang goes the mrs new sofa..... still, priorities, there is always the patio furniture to sit on.

 

not sure on the coil pack........should be ablle to cope with idle even is the insulation is breaking down under "pressure"........completely blown front lambda ??

Code P1131 ?

Shaun

 

fuel pump related.

 

The verdict was......



............MAF

 

Fooked ECU?

 

Either MAF or lambda...........I had a 50-50 chance and picked the wrong one LOL

Shaun

 

Maf replaced but now the turbo holds back on boost at around 0.5 bar. Any suggestions?

 

Proper ecu reset required, laptop job or a "stealer".

dunx

 

Is the CEL light still on ?

Shaun

 

No, light is off
