I have a 96 I30, When accelerating the car makes a chirping type sound then dies out. I have changed the cam,crank,and knock sensors. Checked all coil packs. Put two different ECM in the car. The OBII says EMC memory error. I am lost does anyone have any suggestion other then to junk it. It has 109k on it. The CEL is not on the abs light is on. Please HELP
