What makes spark plugs go bad?
Carbon Buildup Causes of a carbon-fouled spark plug include a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture, dirty fuel injectors or idling your vehicle for too long.
When does cold, engine shakes and hesitates during acceleratio?
After the vehicle sits overnight (cold engine), during idle, engine vibrates and after about a minute vibration’s gone and comes back again a minute after – this cycle goes on and only stops when the engine becomes hot. When driving cold, i notice that the engine does not have enough power as before. It hesitates and shakes when going uphill.
What happens when you start a car in cold weather?
When you start the car, you will notice that it idles high for a period of time until the engine warms up. This is the enrichment cold start process. This is done with what is called a cold start injector which injects more fuel into the motor until the engine reaches a specific operating temperature.
Is there check engine light for intermittent stalling?
Many times, there will be no check engine light and no fault codes to give you a clue as to what might be causing the engine to stall. So the trick to diagnosing an intermittent stalling problem is to catch the vehicle when it’s acting up — and that rarely happens when you have the vehicle in your shop.
Why does intermittent stalling occur in a car?
One of the more unusual causes of intermittent stalling we’ve heard about is a defective vehicle speed sensor. When the vehicle stops moving, the PCM may not engage the idle speed motor (carbureted engines) or idle air bypass motor (fuel injected engines) so the engine will idle normally.
How to diagnose no spark or weak spark?
Diagnosing no spark, weak spark or intermittent spark issues First is separating the issue between switches or the primary ignition components like the stator, cdi, coils, trigger coil or possibly plugs or plug wires or plug caps.
When does a car engine have no spark?
If a connecter becomes 100% disconnected or if a wire gets cut then the switchwill no longer turn off the engine but the engine will still start and run. Diagnosing no spark, weak spark or intermittent spark issues
What causes a no spark condition open loop?
If after unplugging the 4-plug connector there is no spark or the spark still looks weak, this tells you that the problem is in the major ignition components like the stator, coils, cdi, spark plugs, spark plug wires, possibly a short in the wiring harness, a bad trigger coil or on EFI models your Injector Coils are bad (they measure 19-20ohms).
Where is the spark on a club car?
