Thank you for using just answer.
The problem with the air system sounds like a bag leaking,a pump problem,or it might
just need recalibration.To recalibrate it needs to goto ford.If the bag is leaking it needs to
be replaced.The pump if bad needs to be replaced it could cause this.
OK the check engine needs to be scanned.A local autozone will do it for free.Your
problem sounds like a bad coil.If the coil goes bad it wont let the cylinder fire causing the
skip.But it could be a bad fuel filter also.If you scan it and it has a misfire code on the
cylinder its the coil.
