Hard to answer that without knowing the year, make, model and engine info. Whenever I see "lean condition" I look for vacuum leaks first.
NO. That means the engine is running too hot. Check cooling system.
Yes
No , ABS is the anti-lock brake system
Crank angle sensor
No it will not. YOU have another problem.
I had those symptoms and finally had the dealer look at it. the problem was with my cooling system and temp sensor. the car was running hotter than the temp sensor was indicating and the cooling system was not working properly.
The year, make and model vehicle would help.
I would say a badcam or crank sensor. if not scan system for codes
Vehicle running hot? and fan trying to cool it down Bad temperature sensor?
A bad alternator/generator would cause a 'no charge' in the system, which would drain the battery while running. Also a shor tin the wiring may cause a false indicator light.
A bad throttle sensor can cause engine jerking and rough running. A test of the computer codes should show if there seems to be a problem with the sensor.
No, a bad crankshaft sensor would cause the car not to start and run.
