Lumpy idle

[peisden]

Have an evo7 which is very lumpy at idle. Checked for vacuum leaks already. the strange thing is that when the AC is on the idle is good. Also with the lights on i have much better vacuum. NE1 can help?

Is the map on ECU standard I'm not sure if they are like a 4 where if you disconnect battery for a while then re connect then start up and it will re learn the idle you have to leave it ticking over then after 3 minutes turn everything on heater,rear heater,lights ect it then learns under load that's if it the same as a 4.
