What to do about idle air control valve?
I’ve replaced the injector, idle air control valve and the intake temp. sensor. I’ve checked the wiring somewhat, but need to find a diagram and really get into it. Any suggestions of areas to look first?
Where does the fuel pump go on a Honda ATV?
A fuel pressure check would be a good idea. You can make your own,,do a search on YT to show you how,,,its not expensive to make one. Good luck. There aren’t any additional filters if the bike is stock, the fuel goes straight from the tank to the pump then from the pump to the injector.
Why does my fuel pump kick in intermittently?
Check your fuel pressure as stu says and if you take the pump apart, check the green and red wires inside to make sure they are making solid contact, I had a pump that would kick in and out intermittently, found out there was a loose wire inside the pump. Thank you guys. The only thing I hadn’t suspected was the TPS. But that makes sense.
What happens to the vacuum gauge at idle?
Connect the gauge to a source of intake vacuum on the intake manifold, carburetor or throttle body. Note the reading at idle, then raise and hold engine speed at 2,500. The needle will drop when you first open the throttle, but should then rise and stabilize. If the vacuum reading starts to drop, pressure may be backing up in the exhaust system.

Why is the exhaust gas recirculation valve on at idle?
The Exhaust Gas Recirculation Valve is a vital emission control device. It allows the exhaust gas to enter into the intake manifold, with the sole purpose of reducing emissions from the motor. However, this EGR valve isn’t supposed to operate during idle, at wide open throttle or before the engine is warmed up.
Is the EGR valve supposed to run during idle?
However, this EGR valve isn’t supposed to operate during idle, at wide open throttle or before the engine is warmed up. If it runs at any of these times, the performance of the engine is affected.
