Ookay, i just bought my 91 camaro. 3.1 v6. Its idling at 7000. Key off its at zero. I'm confused whether its cluster problems? Speedo does not move eith but everything else works. Id take any advice.

I might be a noob on here but this isn't my first time on here :P

 

Idling at 7000 with the car running or with just the key on?

Make sure the cluster is fully seated in the dash. My camaro has a different cluster then yours afaik, but i think how they attach is similar.

 

The cluster has contacts in the back that can get warn or get corroded over time. You may just have to take the cluster off and clean the contacts.

 

With the key on its 0. Running is 7000

 

Ok. Now when you start it is the car running normal or is it running wide open? Anotherwords, is the car actually idling that high or is the tach just reading 7000?

 

He just means the tach is pegged when the power is on and its at 0 when its off.

 

It seems like its at 7000. Its pretty loud. idk how to adjust the idle just to see if it goes down or not. the screw on the throttle it came with no head. so idk how to turn it.

 

Cant be 7k rpms. Unless some got into the ecm and tuned it. That tach is probly 500 to 1000 rpm off at 5k rpm. They are really inaccurate there is a few write ups oon how to fix them.

That screw your talking about can adjust the throttle blade and that will either make the iac upset or happy..lol. the only way you will get massive 4k and up high rpms is if the throttle blade is literly half open

 

Im not 100% sure on the idle screw on the 3.1, but on the 2.8 there is a little plastic/rubber plug on the back behind the idle screw that covers the head. I believe its a torx bit to adjust. However I also believe you dont mess with the idle screw, you do an idle relearn.

It could be a bunch of stuff if the car is actually idling that high. Perhaps a gigantic vaccum leak, a fully open IAC. Those are just guesses though. You need to find out if its the cluster or not. Anybody you know have an odb1 plugin computer that can tell you the actual rpms at idle?

 

if it was idling that high he would never be able to put the car in gear

it would eaither break the rear end driveshaft or trans

not to mention at that high of an idle from a dead cold start would destroy every bearing in the engine

 

Therevis abosuletly nothing behind my screw. Ill mess with the cluster to clean it and whatnot.. because my speedo don't work either so it might be that. Ill keep you posted. Too cold for anything at this time!

 

There is absolutely nothing on the end of the bolt/screw. Il rip apart the cluster, clean it and whatnot. ill keep you guys posted. Its to cold to do anything anymore!

 

True, it was just unclear whether or not the car was actually idling that high.

 

Iac is easy to check. With car running just unplug the connector.
Also screwy grounds can cause all sorts of gauge problem and other electrical snafus.
