boots problem
 

Ok I am having secondary boost problems. This is the weird thing

when i start my car totaly cold my secondary will work fine, but after i

have drove it and shut it off and start it back up the when the

secondary should kik in the boost just drops down to 5 psi and stays

there. I have done searches I have also checked the charge rlief valve

the charge control actuator and the turbo control actuator all seem to

be fine. Is this a vacuume problem? I was thinking when i start the

car the hoses are hard and allow for vacuum, but I dont know this is

just a hypothesis. I will be checking the vacuume hoses and solenoids

under the UIM after I get the gasket. Does anyone have any guesses

what this could be according tho my symptoms.

bump no one

If it works when cold but problamatic after warm-up, then it must be the Turbo Control Soleniod (TCS). Or possibly Wastegate/"Pre-Control" Solenoid failure.

is there any way to test to see if these are working properly.

I've never tested one, but I've seen a few posts that explain the test process. Do a search and I'm sure you'll land a thread with the info you need. Good Luck.



EDIT:
Mahjik must have ESP. He posted the info/thread 2 seconds before I posted mine. THANKS.

I'm in the same position as you are.
When my it gets hot won't even boost pass 5 psi..
Hopefully somebody will help us out.

Plus what is your vacuuming at..

My vacuum use to be 18 to 19 now it is like 14 to 16..

Whew... I'm glad your boots are Ok;).
