I had the codes checked at Autozone and it came back cycl 4 misfire. I have changed plugs, wires, coil pack, fuel filter, air filter, #4 injector, cleaned the MAF sensor & IAC valve. I have checked for vacuum leaks and found nothing. What next?

I bet you have an exhaust valve issue .....I have seen it a few times.....I think there was/is a TSB for it.
