Having problems with your Ford Focus ?
Ive got a focus st170 and about 4000 revs it seems to missfire
When i get between 3000 and 4000 when driving the car loses power and seems to misfire
If you mean in neural it misses this is normal. It has a rev limiter to save the engine. You are bouncing it off the chip at 4000 rpm.
