please help suddenly my car is only runnin 0.5 bar of boost previously was a full bar boost actuator,ecu and boost solinoid has been check and cleaned been on comp no falt codes cumin up no engine managment light either ! someons says my turbo could be ****ed( no smoke or oil) lookin for opinions people help a bro out ????????

 

i had similar fault before,,, spent months trying to cure, in the end i gapped the spark plugs 0.7 to 0.6 and it was fine after,

that 0.1 really can make a difference

 

the boost came back for about five mins the other night does that not sound like a slpit hose or a sensor fault ?? or could that be plugs too ??

 

sounds exactly same as mine, for the hassle it saved me i wish id have bought plugs and gapped em before i changed anything else

not sayin it will be same on yours 100% but worth a go imo

 

had an engine rebuild 4000 miles ago and i would assume the changed the plughs then still worth a go ?? at this stage ill try anything its like drivin a 2.0 sport lol !

 

same prob mate on a 96 wrx.0.5 bar most of the time and get 0.9 for a few minutes and the back to 0.5 bar

 

I had a similar prob on my 93 wrx turned out to be a faulty coil pack

 

i have read a lot of other threads and it seems like this is a real common fault.only problem is that there is a lot of different solutions.from simple to complicated.it seems like 0.5 bar is a limp mode when you have a fault.let me know if you solve it.

 

Mines doing the same still havent cured it changed plugs , coil packs ,air filter ,fuel filter ,cleaned maf sensor and boost solonoid thinking of putting it on a rolling road to see if that picks anything up

 

found a radiator hose loose today.changed the jubilee clip and have had 0.9 bar all day today.
