Hi everyone,

first sorry for my english! my car does not roll very well in recent weeks. My idle is rough and misfire all the time. I can feel the misfire when I ride, especially at low revs. I just install a wideband and the car rolls really lean at idle (14,5-17) and readings varied constantly.

We check the maps and everything seems ok ...

The car is stock and I recently install new sparks and okada plasma coil...

Thanks

 

did you check for exhaust leaks and boost leaks?
