Hi All,

I’m Richard, new member as of this morning. I am the proud owner of an 02 plate Impreza WRX. I have had the car just under 2 years and have a smile on my face every time I drive it.

Recently it has developed an annoying issue the symptoms of which are covered in this post https://www.scoobynet.com/general-te...6-misfire.html . In short if I drive the car hard in 3rd or 4th gear the engine management light flickers and then stays on. Previously after 50 or so miles the light would eventually turn off; however it’s refusing to budge now. I have had the fault codes checked which have reported cylinder misfires, however the car sounds and drives absolutely fine.

Unfortunately I am not the most mechanically minded person in the world so was hoping for some recommendations for people to use in the Ipswich area. I know full well that if I take the car to anyone but a Subaru specialist diagnostics will go on forever and cost me a fortune.
Appreciate any help/advice you guys can offer.

Cheers,
Richard

 

Start by checking plugs and coilpack if you havnt already, possibly maf related.

 

Definitely the nuetral position switch.

I am not far away from you based in Cambridge, but to be honest I wouldnt have any doubt in this diagnosis.

£45 part from your local subaru dealer and about 10 minutes to fit for you.

 

Im having exactly the same issue with my 51 bug. back to the garage tomorrow for him to sort it out

 

What does the NPS do/ activate on a wrx? Assuming it's non jdm and doesn't have AVCS?

 

Just a really confusing and annoying collection of CELs. Most often misfire codes and cam position sensor and sometimes a flashing CEL.

 

Jameswrx..........it's like the EGT sensor on the WRX up-pipe and the "bright switch", Hopeless !! Never forget the car was built by the lowest bidder LOL

Thanks for the info guys. Will be booking this in asap. She is also due an mot so will get this done at the same time. Thinking about using the dealers in Halesworth. Anybody know if they are any good, not used them before?

 

They are a good bunch of guys down there generally speaking albeit limited in their application of real world tuning like almost all subaru dealers but the NPS is a £45+vat part and a 15 minute fitting so really should be bread and butter for them.

 

On my my02 sti kept getting missfire on 4 and the same code coming up,was told its nps so got that done and next day still come on and stayed on ! Car ran and pulled fine so i got simon jgm to remove via the map he did.hth

 

Not good news

The part is only £39.99.

Fitted just under £400.

 

The part cost me £62 and only £50 to fit, why did you get charged 400!

 

Lol, £400! That's outrageous!

 

That was the quote I got today. Obviously not going with it, so need to find another place to have it done! Was told its a gearbox out job.

 

your joking they want reporting to subaru !!!

I work for a dealer , wrx is easy compared to the sti , half hour tops for the wrx ...

rich

 

Okay - i take back what I said about Hammonds then. Totally outrageous !!!

 

All subaru dealers ....

 

There are some that know what they are doing in regards to aftermarket tuning or are at least aware of it lol but they are very rare.

 

Well there's us and with a dyno (which you have used )..... crossroads who built the time attack car .. ummmmmm .,......

you right i agree ..hahah

 

I did say almost all Rich

Stan Palmer
Tileys in Bristol ?

Think that is about it

 

I forgive ya...

 

glad you said tileys,Dave ball knows his stuff

 

Update for you all.

Got the NPS sorted at GBH Motorsport near Colchester. Top guys, knew there stuff and had the part fitted in less than half an hour!

 

Take the invoice to the Subaru "stealers" and show them...

dunx

 

Did this cure your fault mate

 

Yep!

Has not been a problem since. Very very chuffed.

 

Thanks mate. Getting mine done 2mrw!
