ZX2 has been having low idle. Changed the pcv hose, improved but still idles low. Especially when engine is cold. Check the codes and got a PO303 and 304 cylinder misfire codes, although engine doesn't seem to be misfiring. It is also burning spark plug wires on cylinders 3 and 4. Thinking that there was too much voltage getting through I changed the coil, but no difference. Ran a compression check and 130 psi the first try, then 90 psi, and 60 psi. Once engine warmed up the readings increased.
Car almost didn't want to start today. What could be the problem? Are the cylinders really misfiring? Cause I think that would be something I would notice.
