Replaced spark plugs, both coil packs, and o2 sensors. Upon start up, car will run fine for a few seconds, then start to run rough. Scan and will get either #2 or #4 cyl. Misfire code.

Checked compression, average is about 105 on each cyl. But I dont know what would be a good compression.

You have the 2.0L engine?If so it says compression is 188psi so that would be pretty low compression.

Should I find a used head or have this one redone, problem is kind of short on cash. I had to replace the exhaust manifold, it was cracked in two spots about 3" long.

Since the compression is low across all the cylinders I would check the cam timing.
