What can cause intermittent stalling?

Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we’ll get to later in this article.

What causes a car to stall at low speeds?

Common reasons for this to happen: Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine. Loose or corroded wires in wiring harness: An inconsistently firing ignition will result in an easily stalled engine.

What causes a diesel engine to stall?

The most common cause of a diesel tractor stalling is a clogged or damaged fuel cap vent. Diesel fuel caps have vents to prevent a vacuum effect. If the vent is clogged, the engine won’t be able to properly pressurize, and the engine will be stifled and die (source).

What would cause a truck to stall while driving?

There are a large number of reasons why your car might stall while driving. It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump.

What happens when a diesel pump fails?

Symptoms of a failing fuel pump may include: Jerks or sputters at high speeds. Power loss on acceleration. Power loss while driving up a slope.

Was driving and car just died?

There are many reasons why a car may cut out or loose power while running. A car can die while driving but then will often restart if there are problems with the battery or alternator, a lack of fuel, a broken timing belt, problems with the fuel delivery system or if the engine over heats.

Can a bad alternator destroy a new battery?

Can a bad alternator kill a new battery? Yes, very easily. A failing alternator can overcharge, which will damage the battery. An undercharging alternator will leave the battery flat, which speeds up its failure.

When did the GM 3800 Series 2 engine come out?

While the stroke for the 3.8L engine remained at 3.4″ (86 mm), and the bore remained at 3.8″ (97 mm), the engine architecture changed dramatically. The GM 3800 Series II engine, introduced in 1995, is quite a different engine from its predecessor, the Series I engine.

What are the changes in the 3800 Series 3?

The Series III motors include many changes. The upper intake manifold is now aluminum on the naturally aspirated models. Intake ports are midly improved, 1.83″ intake valves (instead of 1.80″ as on Series II) and 1.52″ exhaust valves were introduced in 2003 engines, just before switching to Series III.

Is there a recall on the GM 3800?

Tighten the bolt to 150 Nm (111 lb.-ft.) + 76° using J 36660. General Motors is recalling nearly 1.5 million 1997-2003 vehicles equipped with the 3.8L V6 naturally aspirated engine.

What was the stroke of the 3800 engine?

Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The piston connecting rods were 1 in (25 mm) shorter, so the crankshaft was redesigned.
