Ok...when I am driving right after warm-up (car hits 80C) I can get both turbos to come online with a fairly good transition. Though not as good as I have had before. This was the brief period I had proper boost. Then almost like clockwork exactly when my intake temperature gets to 40 C my secondary does not come online and it falls till redline. Like I said they both kick in with the intake temps down but the secondary fails to activate after 40 C.

I have found that the metal check valve coming from the purge control solenoid is sending air both ways and the green and black check valve going to the pressure chamber is completely blocked. I need to replace these and could what I have found be the culprit?

Also, my pressure regulator solenoid lost its little tip thingy that juts out from its back opposite the electrical connection. I am replacing it and again, could this be the culprit.

Could it be my precontrol or wastegate control actuator? Do I need to order those just in case?

Any help will be appreciated.

 

After some research I have found out that it is more than likely my Turbo control solenoid going bad after a certain intake temperature. Since it is so close to the UIM and ACV it is receiving all the intake heat and goes bad prematurely. The problem has gotten progressively worse so I am assuming it is that solenoid.

Does anyone agree? I will post a reply as soon as I get my parts in and reassemble everything.

 

I seem to be answering my own posts today. Maybe I need to use the search function.

Well, atleast it might help you guys out just in case you have the same problem.

 

I was going to suggest checking your solenoids when hot, but you are one step ahead of me. good luck
