Is it bad to change gears with car off?
As the clutch is open the gear rings won’t grind together when changing. If the clutch isn’t pressed then this can cause issues but will take a bit of time to wear the gears down. With the car engine off, parking brakes fully applied, it would not cause any harm to shift gears.
What does it mean when your car idles for a long time?
The idle of a car engine is kind of like a human heartbeat: You can tell what shape it’s in just by listening. Problems with idle speed —things like slow idle, fast idle, rough idle, or stalling after idling for a few seconds—are symptoms that something is wrong with your engine.
What to do if your car is stalling at idle?
Idle speed is set incorrectly. The Fix: Set idle speed to specs. There may be some type of ignition problem. The Fix: Check and replace distributor cap, rotor, ignition wires, and spark plugs. There may be a fault in the computerized engine control system.
Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
What causes the Check Engine light to turn off at idle?
At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling.
When does a car idle but not shift into gear?
Engine idle is normal but car will not shift into gear. Automatic: Car shifts into gear with a clunk when you release pressure off the throttle pedal. Firm downshift while passing. Down shifting is fine when you suddenly accelerate to pass, but the down shift should not feel overly abrupt.
What causes a car to not accelerate during a shift?
Automatic: The engine revs up during shifts as the throttle is depressed, however the car does not accelerate. The further you press on the gas pedal, the more noticeable the problem is. Manual: As you step on the clutch, the engine revs, but the car does not accelerate. The clutch feels like it is slipping.
Why does my MerCruiser die when I shift to idle?
Sounds like you may have a shift cable that is bad. If that is the case, it is activating the shift interrupt when going into gear and causing the engine to die. Have someone look at the switch to see if it is engaging when you shift. You may have other problems as well, but that is where I suggest you start looking.
What causes engine revs to drop when idle?
3) Once at normal operating temperature, the engine misses badly while idling. It idles smoothly for a second or two, then misses, which causes the revs to drop suddenly, and then the control system seems to increase the idle speed to counteract the drop in revs for a second, and then the cyle repeats.
