I am back working on my oscillating idle problem. I spent most of last year dealing with a health issue.
All the previous changes that I tried did not fix my idle problem. The problem continued to occur on days of around 80 degrees F or warmer, especially in stop-and-go city traffic.
My two latest changes may have fixed the problem. I have not seen the idle oscillation problem in the last several weeks of riding almost every day. These are my latest changes to fix the idle problem.
1. I turn the ignition on without starting the engine, fully open and close the throttle three times, then turn the ignition off. It is my understanding that the TPS (Throttle Position Sensor) is a variable resistor much like the volume control on an old radio. This resistor may get dirty or worn, and needs to be cleaned or recalibrated for a smooth idle. I hope the three throttle twists do both.
2. I then turn the ignition on, wait 5 seconds, and start the engine. This should give the ECM (Engine Control Module) enough time to successfully complete its software initialization.
I will post if and when the oscillating idle problem returns after making these changes to fix it.
