so lately I’ve been having this problem with my Honda Civic EX2 door 2000, when leaving the car idling for more than a minute when I give it a rev my RPM stays between 1500 and 2000. This only happens sometimes not all the times, but mostly when it is warm. I currently have brand new spark plugs, coil packs, wires. Fuel filter, oil change, injectors And also did a valve adjustment recently. I seem to only have this problem when I leave the car to an idol for instance at a light waiting for the light to turn green and I continue in first gear and my car revs between 1500 and 2000 and jerks the whole car if I don’t give it more gas. please tell me if there’s a fix of this.
