What happens when you cut out full throttle?
Starts right up, Idles nicely and revs easily and nicely until just before full throttle. Once you hold it full throttle for about 3 seconds it cuts out and almost stalls but if you let off the throttle it will recover and go back to idle just fine and run great 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.
Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
Why does the throttle stick open when you open the throttle?
Somehow the plastic had jammed just right as to not cause the throttle to stick wide open but to block the air flow into the engine. (Just a side note, never run any kind of an engine without a good air filter. Your just asking to wear out your engine prematurely or worse.)
Why are my Revs not dropping with the throttle closed?
It sounds like a vacuum leak. (a lean condition). One could surmise that this same lean condition could be caused by some crud partially blocking your fuel passages, but then you’d still need extra air. (Maybe the throttle blades have always been a little bit too open to compensate for some issues with the carb, and it is now coming to light?
What happens when I release the throttle on a car?
Now today im riding it and it takes longer to start (Pullstart), and when I give it full throttle, and release it it just keep reving. When I release the throttle I keeps reving REALLY high, then a couple seconds later the RPM’s go down.
What to do when your revs are not dropping?
I adjusted the cables and magic perfect idle again. A tip on the weights determine if the mechanical advance is the problem is to warm bike up return throttle to off hit kill switch then wait till engine completely stops and without touching throttle crank bike.
What causes engine to bog out at throttle up?
1) Lanyard post is corroded internally and needs to be replaced. Moisture penetration tends to accelerate corrosion of the internal magnetic switch terminals.
