Hi all my 95 WRX seems to be stuck in limp mode read the ecu and found fault code 24 idle air control selenoid reset the ecu and fault cleared tested car but still could only get 0.5 bar it normaly did 0.8 checked all vac lines and cleaned the boost selenoid but still no differenance. would it be worth gettin an adjustable boost selenoid to see if that makes a differance.
Any ideas????

 

any ideas ???

 

What kind of dump-valve are you using? Try refitting the factory recirc, if you've running VTA at the moment.

 

Best not to fit a MBC until you have found the fault mate, could be asking for trouble.

Does it rev ok when driving ie past 5k rpm?? If it is limp mode it will restict the revs.

Take it you cannot hear any sucking/air noises??

When you conect the test wires under the O/S lower dash does the BCS click freely?? While you have the wires conected you could try blasting cleaner through it again.

 

dissconect battery for 30 mins. it resets faults and give you boost again. car may just of had a slight hiccup and gone safe mode. mine has been know to do it if i run any other fuel than v-power. it does not like esso or tescos quality fuels

 

Hi thanks for the replys running standard dump valve, can't here any sucking noises, Still revs fine l cleaned the boost valve with brake cleaner spray.
Reset ecu fine and no faults showing l did fill up with esso ultimate at weekend thought could this cause the loss of boost

any more ideas

 

Esso could be the cause! Get some V-Power in and see.

 

I'll give some a try tommoz and see what happens after a couple of days

 

Not had the car long just ran it on standard 95ron fuel and had no probs but was told that 95 is no good for scoobys thats when l used esso exellium 97ron 4 days ago and thats about when the boost probs started can types of petrol make such a differance between brands
my scoobs a 95 wrx wagon with only mod decated exhaust.

Put some v-power in today but no differance yetstill only0.5psi boost may take some time if this is the problem as their was still some esso excelium in the tank as anyone else had loss of boost due to differant type fuels.
