Learn to diagnose and fix stuttering during acceleration in Ram 1500 DT (2019-Present). Step-by-step guide with symptoms, diagnostics, and repair instructions.

Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the negative battery terminal before working on electrical systems.
•Relieve fuel system pressure before replacing fuel components.

Symptoms

•Stuttering or hesitation during acceleration
•Rough idle when stationary
•Decreased power output
•Check engine light illuminated
•Poor fuel economy
•Engine misfire sounds

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored trouble codes.
2
Inspect the fuel system, including the fuel pump, fuel filter, and fuel injectors for blockages or malfunctions.
3
Check the ignition system components, including spark plugs, ignition coils, and wiring for faults.
4
Inspect the air intake system for obstructions or leaks that could impact airflow.
5
Test the throttle position sensor (TPS) for proper operation using a multimeter.
6
Verify the transmission fluid level and condition, as transmission issues can also cause acceleration stutter.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils from each spark plug.
Remove the old spark plugs using a spark plug socket. Inspect for wear or damage.
Install new spark plugs, ensuring correct torque (typically 13-15 lb-ft for most spark plugs).
Reconnect the ignition coils.

3. Check and Replace Fuel Filter

Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Locate the fuel filter (usually along the fuel line).
Disconnect the inlet and outlet lines from the fuel filter using a wrench.
Replace the old fuel filter with a new one, ensuring the flow direction is correct.
Reconnect the fuel lines and reinstall the fuel pump fuse.

4. Clean or Replace Fuel Injectors

Remove the engine cover if necessary to access fuel rail.
Disconnect the fuel injector electrical connectors.
Remove the fuel rail by unscrewing the bolts that secure it.
Carefully remove the fuel injectors from the rail.
Clean the injectors with an appropriate cleaner or replace them if necessary.
Reinstall the injectors and fuel rail, ensuring proper seating.

5. Inspect and Clean Air Intake

Remove the air intake hose using a screwdriver or pliers.
Inspect the air filter; replace if it is dirty.
Clean the throttle body with throttle body cleaner using a soft cloth or brush.
Reattach the air intake hose securely.
