Ok I check all the vaccum lines and they seem to be in good shape and functioning. The precontrol and the other solienod are connected correctly. So any ideas. The problem just happened out of the blue, other than the boost issue she is running like a top.
If you say check your vaccum lines it might help it you told me what ones your talking about. thanks

I'd first check the pressure tank behind the power steering pump. This is the one reponsible for holding one of the actuators open.

When I had the same problem, it turned out that the nipple hooked up to the tank broke off.

Keep in mind visually checking everything could do you no good. A hose could have a rip in it which you can't see and will only open up under pressure.

An actuator may be leaking or a solenoid could be stuck. Could be a BUNCH Of things

So I guess if I replace all of the hoses from actuators to the soleniods that should rule out the vaccum lines? The solenoid under the UIM is the ones I should be looking at correct. Those are the ones that control the secondarys.


I do here the secondaries blowing but it sounds like its just getting vented off .

thanks

Check your CRV valve for proper operation.(This is the brown BOV looking valve that is connected to the secondary turbo piping behind the crossover. Also check the 1" hose that connects the valve to the y-pipe. Mine was cracked and venting secondary pressure out. ......To test the CRV, try to blow threw the valve without vaccum applied.( you should NOT be able to blow threw)......Apply vaccum to the valve and you should be able to blow threw it. Next step is onto the vaccum hoses themselves then the solenoids.
