Hey freaks, been experiencing issues with my 2007 fit for a little while. Engine is currently misfiring while engine is idling, also when accelerating car feels with no power, pretty much like a spark plug issue but no check engine lights or whatsoever. Spark plugs were replaced with original NGK according to specs of the car, it has 4 brand new Hitachi coils (Bought at honda dealership), valve adjustments were done recently, fuel filter was replaced, Oxygen sensors both replaced (downstream and upstream), camshaft sensor was also replaced but it is driving me crazy. I’ve owned this car for 14 years and I’ve been the sole owner. Any suggestions will be appreciated.

 

Did you ever discover what was making the misfire?
