The Five Steps to Diagnosis
Step 1. List your car details: 91 Integra, 155k (after searching of course)
Step 2. List you car mods: 8lb Lightened Flywheel, AEM FPR, BLOX IM, MSD Wires/Cap/External Coil, JG Bored 62mm TB
Step 3. List your problem: Car occasionally stalls when engaging the clutch (coming to a stop). Idle is 800rpm but rough. Car restarts fine after stalls, has no other problems, no power loss, no stuttering, nothing.
Step 4. List what you have checked to date: No codes are being generated by the ECU. Grounds are solid. No vacuum leaks detected. Recently cleaned IACV. Injectors, cap, rotor, plugs are all new. My theories include: bad MAP or TPS sensors (do not know how to test), bad dashpot, bad ground or positive battery connection, bad fuel relay, sticking IACV?
Step 5. You the reader respond with your theory, idea, and method of testing for my problem

that will do it......i had/have the same issue. the ECU can't compensate for the fast drop of engine idle speed when coming to a stop so it stalls out.
the fix: have your engine idle speed raised a little. open up the idle scew on the throttle body. if that does not work then you need to have the ECU re-chipped and have the moving idle speed modified/adjusted.

Thanks, but thats not the problem. I had the lightened flywheel installed for 1yr BEFORE this problem started. Yes, every blue moon the car would stall because of the flywheel, but now it stalls all the time, and idles rough. Its not the flywheel, its something additional. But having the flywheel doesn't help the problem it aggrevates it. I'd like to solve the issue before i just raise the idle speed.
