Symptoms
Stumbling, hesitation, sputtering, rough running or stalling at low rpm. If it only runs with the choke off, suspect the EGR valve.
The fix, step by step
- Corsetti says the most frequent problem is simply a loose or broken vacuum hose or wiring connection, so check fuel and ignition basics, then every vacuum line, before blaming the carb.
- Rebuild the factory carburetor and check the EGR valve while you're there.
- Above 3,930 feet, check the High Altitude Compensation system, which a Weber carb bypasses.
- Trucks over 200,000 miles will likely need a full set of vacuum hoses.
