How long does it take for idle RPM to drop?
Sitting at a stoplight, after about 20 seconds, the idle will drop to about 200rpm, causing the whole car to shudder. It’s just like it’s about to stall. Then in like 2 seconds it’s back to 750rpm or so. No CEL lights or DTCs are thrown. Oh well.. at least it doesn’t completely stall I guess.
What does blip throttle and Revs hang mean?
Blip throttle and revs hang = rich/lean? are adjusted towards the lean side. If on the other hand a quick blip returning to the idle rpm the bike is running a little rich. Does anyone know of the underlying mechanism to this analysis?

Why does my RPM drop when sitting idle at traffic lights?
While I’m sitting idle at traffic lights I put the car into neutral. The engine stays idling at about 1000 RPM. However every now and then it drops down to about 500 RPM and then quickly back up to about 1200 then goes slowly down to 1000 and stays there for a bit until I go again or it drops again.
What happens when engine RPM drops below 800?
However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is failing, your vehicle will stall instead of slowing to an idle after the release of the throttle.

What causes reverse switch to break during idle?
Vibration induced by certain RPM’s can cause the reverse switch spring connection to break contact briefly, turning the limiter on intermittently – try grounding the wire and see if the problem goes away. (I’d guess, from info so far, that this is the most likely culprit)… I cleaned the carb after the problem started.
