Ok i just experienced a issue and not sure what it could be, i have only owned the car a couple of weeks and it has been performing flawlessly,

After a nice short slow drive i then put my foot down to have a clear out :P however as soon as the turbo kicked in the car felt restricted and wouldnt rev any higher when probably around 4k this happened a couple of times but not every:S

Would anyone have any ideas what this could be

Kind regards

 

It felt like it was going in limp mode :S

 

Details of car,spec etc.

 

2004 wrx stock 58,000 miles

Last service 3k ago

 

Check all pipe work,including intercooler,sounds like a boost or vacuum pipe has blown off or split.

 

Forgot to mention it does not happen everytime, its only happened twice.

So it cant be a blown off pipe nor a split pipe as the car feels and sounds the same

Thanks

 

Have you got a code reader? Could be a failing sensor.
You get any CEL when it happens?
Do you have a boost gauge?
Does this happen when cornering or straight line?

Could be loads of thing causing it.
Bad sensor,failing fuel pump,bad spark plugs,poor fuel,detonation......etc etc

 

Could be early signs of the up pipe cat collapsing

 

Well I took her out for a boot this morning and it didn't do it once and it still feels awesome so not sure what the issue was, will probably get it on diagnostic today, thanks for replies

 

Don't pay silly money for diagnostics,you can buy your own kit for under 20£ to read your own ECU.

 

or pop in to see a local member who already has such equipment lol

 

UPDATE

I took the car to Chevron in stafford for them to have a quick look and stick it on the diagnostic

No faults

The car is still running perfect bar the twice it had a loss of power/limp mode sort of thing

We think its the plugs so some new NGK spark plugs are to be fitted on friday

Happy days
