Idle Adjustments
Hey guys. Just wondering if someone here might have a little advice. I have an 85 RX with a 12A motor. It starts first try ever time, and pulls fine, but dosen't idle very well below 1500rpm. It dosen't stall below that but it's up and down the tach between 900-1200. I'm thinking it might be an exhaust prob. but I'm looking for other suggestions...anyone?

Hunting is usually a good indicator of a vacuum leak. Get a can of starting fluid and spray until you see hear the engine roar up some. Trace it down until you find the leak.

spray it around the hoses, and if you do have a leak, you'll hear the engine respond to the starting fluid. Once you have the general area nailed down, you'll be able to spray specific lines until you find the one leaking. At least that's what worked on my car.

I dislike using starter fluid personally since it can land on hot areas if not careful, exhaust manifold, etc, and combust easily.
I take a propane torch, unlit, but with gas on, and trace vacuum lines. A vacuum leak will suck up the propane and increase the idle without getting messy and potentially dangerous starter fluid on hot engine parts.
