TROUBLESHOOTING GUIDE
F-61flowchartTroubleshooting steps 5-8 (POOR ACCELERATION)
5
INSPECTIONCheck for correct ignition timing at idle (page F-75). Ignition timing: 10° ± 1° BTDC. (Connect GND-TEN terminals.)
RESULTYes
ACTIONCheck if ignition timing advances when accelerating. If advances, go to next step. If no advance, check ECU terminal voltages (page F-127).

INSPECTIONCheck if spark plugs are OK. Plug gap: 1.0—1.1 mm (0.039—0.043 in). Inspect wear and carbon buildup, burns, damage and deterioration, damage.
RESULTYes
