I had troubles since a month with the engine misfiring at high load/rpm, and going fine after,
so i began by changing the spark plugs : same problem
then, i realised a was low on fuel, so i topped, and same problem,
then, i changed the fuel filter : same problem
And a week after, the problem was more present, it was sometimes putting the car in error mode, no power, no revs : i had to switch off/switch on and if was running fine, for a few minutes, ...
So i decided to change the 4 coils (i have a spare K20a2 engine, so easy to swap parts/sensors) : same problem
I swapped the Map sensor : same problem
I swapped the throttle position sensor : same problem
So i decided to install the OBD kit i bought a month ago (i should have begin with this...), it was very easy (a 30min job).
And the OBD told me that the crank position sensor was faulty, so i swapped it :
The engine is now running perfectly
The lesson here is to install the OBD kit before trying to change all engine sensors
