Hey guys I was resetting my ECU to see if my engine light would go off and instead of good news i got bad news, an extra code. I was getting codes 14 + 21 but now i'm getting a code 8 along with the other two! I read around and people are saying that i need to replace my dizzy for the code 8. Also idk why i'm getting an IACV code when my car idles at a steady 7-800 rpms. I did notice that my engine is a little boggy until i hit higher RPMs. Could any of these codes cause that problem?

Car Specs: 94 Del Sol Vtec w/ JDM B16 swap.

Any suggestions or ideas would be highly appreciated. Just trying to get my car running correctly. The JDM swap has less than 100 miles on it.
