Still having high idle problem on 88 Jeep Comanche (4.0l)
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:
http://jeep.off-road.com/jeep/articl....jsp?id=257836
http://jeep.off-road.com/jeep/articl....jsp?id=257985
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.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
Well, I got in there with a brush and solvent, and took off some stuff on
the sides (beside the butterfly valve, for lack of the technical phrases).
But it's opening and closing easily, and it's stopping when it hits the
metal stop on the outside of the throttle. But is it perfectly clean? No.
Should I scrub some more?

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)

as a source of the problem. Oil in the CCV system doesn't help either, and
cleaning the orifices is in principle also easy.
