Hi. I have a 2012 civic si, it has 280k km on it. Recently I’ve experienced a misfire only around 2000 rpm. The car idles fine, and is also fine under heavy load, just not lightly cruising. My dipstick smells of gasoline.
Here is the freeze frame information.
Okay here’s all the info from the code reader on the freeze frame
Fuel sys1 cl
Fuel sys2 n/a
Calc load 22%
Ect = 185f
Stft = -11.7%
Ltft = -10.1%
MAP = 7.6 inhg
Engine rpm = 2009
Veh speed = 20mph
Spark adv 44.5*
Iat 87.8f
Maf 1.13lb/min
Tps 16.8%
Run time 260 seconds
Command evap 53.7%
Fuel level 45.4%
Baro 27.7 inhg
Ecu volts 12.3v
Load value 18%
EQ ratio 1.026
Rel.TPS 7%
TPS B 33.3%
ACC pedal d 28.6%
ACC pedal e 14.1%
Command tac 7.4%
I cleared codes after and swapped ignition coils, tried to get th code to come back and the only thing that changed was the ecu volts was around 13.5v. Cylinder three misfire code is permanent. But won’t show cel. When the pending code showed, the cel vsa and power steering lights came on
