Why does my bike shut off when I give it gas?
False Idles Rich bikes are getting too much gas, so they idle high but lose power when given initial throttle because they can’t burn all the gas. A key clue is that the issue gets better as the bike warms up. Extremely lean motors can also stall out completely when given some light throttle.
What causes a boat engine to have a rough idle?
A misfire may occur when your engine is idling, causing a rough or uneven idle. Misfires and rough idling are difficult problems to isolate, since they can be caused by many system malfunctions.
What causes a car to run lean at idle?
If the root cause is an electrical problem within the idle air control valve itself, you will likely have to replace the IAC. A vacuum leak is a hole in a vehicle’s air intake system behind the mass air flow (MAF) sensor that allows unmetered air into the engine. This throws off the expected air fuel ratio and causes the vehicle to run lean.
What causes rough idle and car misfire?
Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on the accelerator. A rough or uneven idle can be an indicator of an engine that is misfiring. The air/fuel mixture is disrupted which can cause the engine to jump up and down.
What causes a car to idle with a skipped tooth?
Incorrect cam timing may lead to a rough idle, misfires, or a stalled engine. A skipped tooth could be caused by a belt that was too loose, either due to a failed tensioner or incorrect tensioning procedures. A camshaft gear that has slipped on the camshaft may exhibit similar symptoms, but is harder to diagnose.

How can I keep my car at idle?
Step 3 – Engine vacuum is a sealed system and must hold a specific amount to maintain proper idle conditions, inspect the engine vacuum hoses and intake gaskets. Step 4 – The air intake boot or tube is used to deliver air to the intake system of the engine.
What does it mean when your car Idles smooth?
Smooth idling indicates that your engine’s fuel and air are mixing just right. What is rough idling? If your vehicle’s idle is rough, possibly rising and falling, or having difficulty maintaining a steady rate of rotation, you may have a problem that needs fixing.
When to remove an idle air control valve?
Because of the nature of this valve (large air volume processed) it should be serviced when a tune up is performed to remove “coking” which will hinder the valve’s performance. To perform a rough check of the idle air control, remove the valve while reconnecting the wiring harness.
