What causes a Chevy Suburban engine to stall?
Stumbling and poor idle can be caused by air or fuel starvation so make sure that those filters are OK. I think that my own problem is caused by dirt in the fuel tank plugging up the fuel intake screen. I think the dirt falls off when the engine is shut off.
Why does my car stall at highway speeds?
The engine may start and idle fine, but run out of power or even stall at highway speeds. If the engine starts right back up after stalling, the likely cause is low fuel volume delivery because of a weak pump. If the engine is running normally one minute, but suddenly quits, loss of ignition may be the problem.

Where is the speedometer located on a car?
Where is the speedometer sensor located? The speedometer sensor is located in the transmission of your vehicle and is designed to register the driveshaft’s rotational speed. The sensor delivers this information through the speedometer cable and to the vehicle’s computer, which converts electrical pulses into a numerical speed.
What happens if your speedometer does not work?
If the speedometer sensor is not working properly, the speedometer will be inaccurate; potentially leading to speeding tickets or unsafe driving situations. The symptoms noted below will give you an indication that a problem exists with your speedometer sensor: 1. Speedometer does not work

The bounce of the tachometer needle happens when speed is constant under little to no torque, anywhere between 30-58 km/h, the RPM ranges 1300-1800-ish {if I press or release the accelerator slightly the RPMs stay steady, and the bouncing tach needle stays steady}.
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.
What causes an engine to stall at idle?
If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes. A faulty idle speed control circuit may also allow the engine to stall when idling if it fails to compensate for idle loads placed on the engine by the charging system or A/C compressor.
What’s the difference between a stalling engine and a not starting engine?
One of the main difference between and engine that will not start and one that stalls while in operation is the ability for the computer to detect the problem.
