Hi Klaus,

>If your car is a non-turbo, clean and check the PCV and the small line for >blockage.

My car is NA and I don't think there is a PCV valve? There's a flame trap
that I threw away.
I did find a small vacuum line plugged and the EGR and intake manifold
plugged and cleared that stuff. I cleaned the Throttle body, mass air sensor,
and the car ran ragged for a while, with what seemed like giant vacuum failures
showing up with the brakes being messed up. Maybe there was some giant vacuum
leak with some chunks of that crap getting stuck in the EGR diaphragm?
It's got better and now the only funkyness is that the car races some at startup

What do you think about oil leaks from a plugged intake manifold/EGR,
will they quit after clearing the blockage?

After doing that job, I'm wondering if it's possible to remove throttle body
and EGR valve body and smack the blockage out of the intake manifold without
removing the manifold (Which is a serious pain where you sit down)
How long does it take to clog up that EGR port? Is it a function of
miles , time or what?

Regards, Bill
