I have a 1.5L carby 1993 civic hatchback, and it runs well except I have an idling issue. It will stick at 2000rpm for the first 5-10 minutes of driving, and then at a set of lights of when I stop the idle will just drop from 2 straight down to 1000rpm and stay there. Also, on a short trip where the idle does not drop below 2000rpm, when I turn the car off it will burble and keep running even when I have turned the key off. However, this only occurs when the rpm is at that 2000rpm range, not at 1000. What is going on?
