A visual inspection showed that new spark plugs, spark plug wires, ignition cap, and rotor have been installed. Now when starting the vehicle it revs to around 2,200-2,500 RPM then VERY slowly idles down. You don't want to have to floor your gas pedal and wait a few seconds for your vehicle to move. As soon as I let off the gas, it stops completely. There are a number of reasons why an engine might misfire while it is idling. The car seems to be very shaky and judders at low rpm and has lost a considerable amount of accelerating power. Just don't overdo it. I have tata indigo ecs cr4 bsiv diesel currently purchased , i noticed rpm fluctuations when pressed clutch at idling, also it gives black smoke even if revved 1700 rpm. My car used to idle at 800 rpm, but now, when the engine is cold, it idles at about 1500 rpm, going down to 800 as the engine warms up.
