Is it normal for the engine in my 85 gs to shake a little when it is idling between 1,000 and 900 rpm's? Would this be considered a rough idle?

 

I don't think anything is supposed to shake. My 82 GX shakes when it idles ~500 RPM [that's when warming up.]

Does it, by chance, have a miss at idle as well?

 

Yeah it has somewhat of a miss. I checked vacuum with a gauge and it said 17 which is about average right, rebuilt the carb, new plugs and wires

 

Does anyone know what might be the problem?

 

Yeah, the problem is you haven't done a search.

 

Drifting Rex, I appologize for cdrd51's behavoir.
You see, he just got an Rx-7 and still behaves like he's a 16 year old with a tricked out Civic; A rude, obnoxious arrogant punk.

Have you tried a new cap and rotor? Test-light your plug wires. That'll tell you if it's a fuel delivery or an electrical problem.

 

it also might be as simple as a carb adjustment hard to tell from my monitor.

 

Well, thank god I have somebody to apologize for me. Thanks dad.

Or it could be idle mix screw out of adjustment. Or timing. Or a vacuum leak. Or some other thing. But all those answers are already here, at the magical end of the e-fingertips, waiting for a search.

 

Sorry, Sterling but that was kind of funny.
