Lost compression in cylinders 2 & 4 at the same time 2 is 20 psi and 4 is 30 psi. Cylinders 1 220 and 3 185. What could corser those to cylinders to drop compression and the same time.

Multiple cylinder misfire, 2&4 misfiring. I've checked and swopped coil packs and spark plugs, no change in codes. I've also swopped around injectors 1 &2. No code change. Checked for leaking inlet manifold no leaks. Has anyone go any ideas what the problem maybe. It's a 1.8 lt 06 corolla sedan thanks Dan
