| Engine Noise Is Excessive | Air intake or exhaust leaks | Inspect the air intake and exhaust systems for air leaks; replace the muffler if necessary |
| Engine Runs Rough or Misfires | Ignition system issues | Inspect the spark plugs, clean or replace the spark plugs if necessary; test the ignition coils using a coil on a plug tester (or in-line spark tester) to isolate the faulty coil, replace the faulty coil if necessary; check the coil wiring, inspect connectors and wires for breaks, and test continuity |
| Engine Shuts Off Unexpectedly or Dies during Deceleration | Emergency Stop (if used) | Make sure that the Emergency Stop circuit is not energized |
| Engine Speed Surges Under Load or in Operating Range | Fuel system issues | Inspect fuel lines and connections for leaks (spray soapy water along the lines and at connection, bubbling indicates a likely leak location), repair if leaks are found; check for fault codes using the E-Controls tool and troubleshoot as specified in the E-Controls manual, inspect the bore of the throttle body, clean if necessary or replace if worn; inspect the pressure regulator and EPR assembly for damage, the valve located inside the assembly should move freely, clean or replace if necessary |
