Engine/Transmission (1994 - 1998) Idle issues

[DSpringstead]

I just got back from a 700 mile round trip. I noticed that when I run 65-70 mph for a couple of hundred miles, After I cool it down, shut it off, when I get ready to fire it up again the idle is way low . Sounds like about 200 rpm lower of where it should be. I can rev it up a little & the RPM's come up. Anyone have an idea why it does that? It doesn't seem to keep the idle set. Could I be sucking air

You mean to tell me that NOBODY even has a clue???????

Is this a first for this problem?

Can it be timing? or just simply resetting the idle? or could it be more involved?

How about a little more info, like the model year, type of trans, modifications, etc.

Getting it hot could be 'melting' some grease and lubricating something that's getting a little dry and/or rusty. Spray PB Blaster on the shaft at the back end of the p-pump where the idle speed is controlled. Work it in good. Then set the idle.

I have a '97. No fueling mods, AEM intake, ATS 3 pc EX manifold with a 4" exhaust out the back. It's basically stock. Could it be linkage?

There is an idle adjustment screw on the back of the IP. A little difficult to reach, but doable. A small adjustment goes a long way.

Idle speed, auto trans 750-800 rpm with trans in drive and a/c on.

Manual 780 rpm trans in neutral and a/c on.



Mine rpm starts out lower when cold but when it warms up it is normal.

If not a linkage, a long shot would be the overflow valve sticking after heavy use and resulting in low fuel pressure until it frees up.

I have a Torq-tek overflow valve that I replaced due to losing prime on fuel system from internal leakage and it made for longer cranking time than normal 12v's
