Drive the vehicle certain conditions for checking poor power/acceleration.
Is there poor power/acceleration?
![]() | → Sudden poor power occurs and impossible acceleration above certain rpm while driving. ▶ Go to "Poor acceleration" inspection procedure. → Lots of black/white smoke is discharged through muffler at accelerating. ▶ Go to "Exhaust fumes is discharged" inspection procedure. → Engine hesitation/poor acceleration occur at cold starting. But symptoms disappear after warming up. ▶ Check/repair the glow plug. ▶ Inspect carbon deposit/damage/blocked/widen hole of the injector nozzle after remove the injector. ▶ Remove the fuel filter assembly and check the state of the fuel which remains at the fuel filter. → Slight poor power occurs in specific load condition. ▶ Inspect that ECM/PCM has the right IQA code written on the surface of each injector by scantool. ▶ Go to "FTS" inspection procedure. ▶ Go to "ECTS" inspection procedure. ▶ Go to "RPS" inspection procedure. |
![]() | ▶ Go to each inspection procedure after checking poor power/acceleration. |
