Hey guys need sum help. My impreza wrx keeps losing boost now and again. Drops from 13-14psi down to around 7. If I turn ignition off and back on again it's ok. I'm thinking an electrical problem, any help appreciated peeps.

Is it a classic Impreza?

Do you have a engine management light come on? It might be worth trying to read the ecu codes if it is a classic?

Mink

No m8, it's a blobeye 2003. No the engine management light has not come on.

What conditions does it happen under, for example is it always hard driving does it happen? Does it happen every time you use the car? Or just sometimes?

Mink

It's very random. Sometimes first thing in a mornin, sometimes after Iv been stood in traffic then sometimes when I given it abit if stick. Can't really pinpoint it.

Will it not boost over 8psi? I had this problem but just whipping the negative off the battery, leaving it 10 mins and reconnecting it permanantly sorted it. From what i read the car didnt like something i did so was only boosting off the wastegate, which is 8psi .

Mink

No but only sometimes, Iv been told it might be the turbo boost solarnoid that needs cleaning! Any ideas?
