After cleaning the erg ports. The car is dying out after taking the car for a ride. Check engine light came on and the code was 3, map sensor. Changed the mapp sensor and car is stil dying out. When it feels like its going to die out I pulled the wire out of cylinder 4 and it somewhat have gotten but still not smooth. But once I drive it dies out when I come to a stop. I disconnected the wire from the iac and it shut off. Did a compression test and that came back fine cylinders around 150 each. Also check my other posting and you will see my other issues. I don't know what to do now. Help please
