The engine idling is unstable in the driving state of Isuzu, and it goes back and forth 4 or 5 times at 800 rpm and 1000 rpm.

As for the problem of stopping with fuel, since the existing car is not seen, if the engine shakes when stopping after driving, it may be caused by excessive carbon deposition in the throttle valve, idle motor, intake valve, intake pipe and combustion chamber, spark plug and fuel nozzle. Because these carbon deposits will block the idle channel, the idle motor will be stuck or beyond its adjustment range, resulting in low idle speed, unstable idle speed, oil collection and flameout. Also pay attention to check whether there is a fault in the carbon canister, which leads to the rich mixture when the engine is working, which leads to the rich mixture when driving at low speed, which leads to the flameout of the vehicle after receiving oil. I hope my answer is helpful to you.
