94 idle speed adjust ?

I think I got the Idle Air Control valve problem solved but it seems the
idle speed is too low, right at 500 rpm. What is the idle speed supposed to
be and where is the screw to increase it. I've looked aronmd but can't see
anything obvious. Any tips appreciated.
tnx

Re: 94 idle speed adjust ?

Don't know anything about the original problem which started this thread,
but I am afraid that you are missing something. The idle speed of virtually
every fuel injected engine is set and maintained by the PCM (computer).
That's what the IAC is for. There is no way to change the idle speed setting
except by re-programming the PCM (and there should be no reason to do so).
If the idle speed does not follow the computer-calculated setpoint, a
trouble code will usually be set.
BTW: Take a look at the VECI sticker under the hood. The fact that idle
speed is computer-controlled and not adjustable should be clearly stated
there.

About 650 -700

There's no screw, thats why you have a IAC valve.

So maybe you don't have your IAC problem solved :-)

Even if you cleaned the IAC valve, it could still give you idle
problems. Might be time for a new one.

Re: 94 idle speed adjust ?

thanks for all the help..
No wonder I couldn't find an idle adjust, I'm too old and never worked on
these newer critters that are fuel injected and computer controlled..
I'll be be looking for a good deal on a IAC or try to find a good used one
at pullit parts.
O'Reillys tell me that it is a Ford ony product, that they can order.

I wouldn't bother buying a used one as you won't know how long it will
last. You can buy a brand new one at autozone for $59.99.
