My car is running really really well atm. Purrs like a kitten and all that the only issue I have is that when I start it up in the morning it doesn't want to idle until it gets warm. I turn the key and it cranks over immediatly rpms shoot up and then it immediatly dies. If I catch it with my foot on the gas and keep it from dying it runs just fine until it gets warm and then it idles just fine as well. Which issue do I look at to solve this. It would be great if it would idle when I first turn it on in the morning. Has only started doing this recently with the turn in colder weather.

Any suggestions would be appreciated....

it sounds like an idle air solenoid issue. that's mounted on the front of the intake manifold, far left.

it could also be the idle air valve. that's mounted on the rear of the intake manifold just right of the center line.

I'm trying to sort out just which one of these issues I have and how to tell. While I was poking around under the hood I discovered a ground wire that only has one end connected. Any ideas where the other end should be attached at and if it is causing me any grief...?

You can see in this picture I have an arrow pointing to the bolt that is holding the attached end. Anyone care to take a look at theirs and tell me where the other end goes? It has a quick disconnect in the middle of the wire and a loop on each end.

I was sort of thinking that. Also I don't think the wire is an awful lot longer than would reach in that vicinity. However any pointers on exactly where to bolt it back up would be appreciated.

Ah yes! Well in my case the two pieces were connected and the bolt wasn't through the other end. Making it hard to just hunt for the unplugged connector. Anyways I unbolted that second bolt on top by the distributor and reattached the wire like it is in that picture. Probably won't help with my original issue, but it's nice to know it is back in the right place. :)

thanks for posting the pic lukak. :wink:

the idle air solenoid, iac, is on the front of the intake manifold with the blue electrical connector. those have a known failure mode where the little brass spring valve on top breaks.
Image

the idle air valve on the rear of the intake manifold has coolant lines that run to it's body and an internal wax pellet that melts when the coolant temp reaches operating temperature. it has 2 steps of high idle plus the third step which is a normal idle at between 800 and 1000 rpm. those can get balled up.

on my red twincam vert i removed that valve and replaced it with a banking plate i bought from a member in australia. he has a listing the parts for sale section and has recently added new stock of the blanking plate. it neuters the fast idle when the engine is cold but it also completely cures idle surging caused by a bad idle air valve.
Image

it also appears from your pic that your car has air conditioning and the adjustable idle air controller for that system which is mounted to the firewall. that's another idle air control that i ditch on my twincam cars. i don't use air conditioning and deleting that chunk simplifies the idle controls.
