Hey all, a few quick questions. I've done a bunch of searches and havent found answers to the following:

1. Can you and how should you clean the AMM? I did find how to test it, but want to clean it if this is feasable.
2. How can you test the Throttle Position switch, and the WOT switch?
3. I'm a bit uncertain on where the PCV check valve is. I cant see one on my car.
4. I want to take the Throttle body completely off the car and do a total cleaning, R&R all. Any guidance on this?

My car starts well, regardless of outside or operating temps, but..... I am finding several strange things.

1. Once warmed up, will have sudden and unexplained stall at idle.
2. Little or NO vaccum at the ports for the Vaccum advance and wherever else they go.
3. NO change in idle speed when AIC is plugged or unplugged.
4. Idle is a solid 850 right at startup, does not riase or lower as engine warms.
5. Car feels like it has NO vacuum advance or turbo, and acts as if teh CAT is clogged.

I have a way to go and LOTS things to do, plan to do a full take off, clean adjust replace of all hoses, plumbing, sensors in engine. Set base boost, etc. I will be looking at the Turbo closely this weekend when I take out the whole intake tract up to the throttle body.

It is nice to NOT be in a rush. I want to do this all the right way, wont be putting car on road till September. Dont know about anybody else, but THIS type of stuff is awesome therapy.
All is for a 1986 16V Turbo w/ automatic
