So I'm getting good vacuum using the very imprecise "finger over the hose
end" at the CCV hose, and the TPS sensor goes from about 1 to 5 volts. Is
there some other things I should check?
Today it behaved differently than usual, hitting close to 3000 rpm while
"idling". Usually it starts at about 800rpm when I start it up, and stays
constant at about 1500.
Could having a bad CCV valve be causing my problem? I'm getting some oil in
my air filter as well, and as per these websites, it seems that may be that
cause of the oil:
I did try sealing around the grommets with some RTV silicone, but it didn't
seem to make a difference.
I guess I KNOW that I need to fix the CCV hoses/valves, but can this be
causing my problem with the high idle? If nothing else, I'm figuring that
oil in the air filter probably isn't helping keep the throttle body really
clean, since the oil can get into the air system from there.
