Hello. My car is having problems when the rpms get really low. After the car warms up, when I take turns or slow down, the rpm meter just drops to zero. It even does that no matter what speed Im at if I go into neutral or just press the clutch down. When I try to start up the car again, sometimes it starts up fine, but sometimes it coughs. When it does cough, the coughs get weaker and weaker until I dont see any lights come on or hear any clicks. After a little while of trying to start the car. it eventually starts and then I manage to get home by revving the engine to keep the rpms high. I heard it may be the Intake Air Control or something like that. What do you guys think? Oh yeah, my check engine light does not come on.
