Hi guys I not long had my car and to today I meet up with a couple of other Subaru chaps and we got to talking and looking at each others car when I noticed that everyone else car engine on idle sat level and straight but not mine it's a bit lumpy so I got to checking all the paper work and found a reciept for a fault code reset p2012????? Is this a big problem or something people come across all the time any help would be great in regard to the car it has a cat back after burner exhaust a hks bov (from sumo power not cheapy) and a do-luck panel filter ??

 

Also it a 2005 wrx impreza 2.0 turbo forgot to add I'm alittle worried to be honest cheers for any help

Are you sure you have the right code.......check with the above chart

That's the code on the reciept p2012 inlet manifold runner control??? Thus might aswell be in german lol

 

I recently fitted a new maf sensor and that solved my idling problems but I still get the occasional dip in idle, not sure if I have an air leak somewhere, its not a bad dip but still annoying all the same

 

Hi mate thanks for the reply where did you get your maf from??? See my car on tick over is shaking and rough but as soon as you touch the throttle it's gone

 

I got mine from the scooby clinic, paid £120 for the full unit. You can get the sensor itself for cheaper. It got to the point where if I didn't give some gas at lights to stay above idle I would cut out

 

Have a google on ICVS symptoms..... Might need a clean as they can stick sometimes. My erratic idle cost me £280 for a new one

Ideally you need to take it somewhere and get your ECU read before you go spending money on parts that might not need changing. MAF and ICVS problems would be the prime culprits, but it could be something else too.

 

Yeah I thinking it's got to go on computer but I what it remapped anyway just need to put my headers and up on and new fuel pump in then have it put in and all the little bits ironed out I just thought it might have been a quick fix but I should have know by now nothing is a quick fix or a cheap turn out lol

 

It may well be a quick fix, but best to get it on the computer to save you wasting any money.

If your planning a getting it maples then I'd also suggest giving it a good service first, including plugs. You might find that sorts your problem too.

 

my rough idle was down to a split t piece under the manifold that had a slight split due to heat,

so it may be something silly but get it on a comp before u waste money
