I performed a compression test with the following results:
c1 200psi
c2 140psi
c3180psi
c4 195psi
Alldata says a minimum of 100psi is acceptable, but the cylinders have to be within 25% of each other.
I swapped the sparkplug and coil and still got misfires on cylinder 2.

is 140psi acceptable?

What is the issue with your engine that you had the compression tested? Which engine is it?

If you have a 1.4T or 2.4 tigershark engine it will have a misfire if you get too low on oil. That is the first thing I would suggest checking. Low compression in only one cylinder can mean a few things, but most likely a blown ring or a stuck valve.

I wouldn't feel comfortable driving it with only 140psi while the others are near 200psi. Maybe somebody else can chime in.

Its 2013 1.4T the oil level is fine. I also check check the wiring for going to the injectors and sparkplugs and they were good.
