My 92 RS with 3.1 V6 idles around 1000-1100 RPMs when fully warmed up. Starts around 1800-2000 when cold. Isn't the idle RPM a bit high? It is a stick shift.

Re: What are idle RPMs for the 3.1 V6?

Is your tachometer correct ? Checked for vacuum leaks ?

Thanks. I may actually have a vacuum leak. Just need to find time to check it.

Re: What are idle RPMs for the 3.1 V6?

I connected my smoke pump to the hose by the brake booster. The only smoke that came out was by the air filter. Noting in between. The tach still shows about 1200 as the running (engine warmed up) RPMs. To my ear, the car does run at high RPMs so the tach could be correct but I am not an expert. Any other ideas?
