Hi fellas,
Let me run this by ya,car been brill for ages no prob,then boost drops from usual 15.5 psi to 8psi,tries powering the car a few times,still low boost..on the odd occasion boost returned to normal and all was well.Thought ahhhh..boost solenoid stickin!!No prob,stripped off car and cleaned,refitted and car is the same,took on test for 10 mins,boost at 8 psi and never flickered up at any occasion..This all happened this afternoon,jumped in car to drive home,and after warming up boost was at 8psi for about a mile then all turned to normal and runnig back at 15.5psi,never faultered all the way home[5 miles],,,do we think its just a case of a sticky valve?is there anythin else that could cause this?can ya get a modded version?
Cheers,
Gary

 

Try cleaning it again by connecting the connectors under the dash these put it into duty cyle and the solenoid will open and close then spray in some wd 40 after this re -set ecu .You could also check your oil level it should be around the half full mark not at the high mark.Hope this helps if you are unsure on which connectors do a search on ecu test/reset and it will tell you always forget myself

Good idea mate,may just go for a new one or an upgrade one if its available...as long as thats the prob!

 

any ideas???

 

what model/year ?

 

It's not going into "limp-home" mode is it...?

 

defo not limp home mode,car is a 96 N plate.uk spec..........just a footnote,car has been 100% today.no sign of prob.AS YET!!!!!!!!!

 

I've got my old 3 port soleniod for sale, came off a 95wrx, changed last year in error.

Thanks, Roy

Sorry don't know how to make it clickable. Roy.

 

Sorry to but in, but what exactly does a 3 port boost solenoid do ?

Are standard solenoids 1 port ?
If one was to fit a 3 port, is it a straight swap, any potential problems, any benfits to running it ?

Many thanks.

 

orig solenoids are 2 port, 3 port solenoids are used by some mappers as it gives a greater control of boost, it is definately not adviseable to fit a 3 port to an unmapped car

not even to a ppp'd car, or does it need to be custom mapped in ?

 

Will need to be mapped, I'm afraid

 

Update guys..........car has been 100% since cleaning out,guess it was the solenoid and it just took a bit of getting goin!!Thanks all...if anyone needs a 3 port solenoid,grade A breakers are sellin them..£30+vat...very resonable i think.
Ta,
Gary

 

hey guys when a 95-97 wrxs overboost does limp home mode happen after every overboost.
