...actually a resistor in my ecu is already burnt out causing me idling problems. i just bought a new resistor but haven't installed it yet in the ecu. the mechanic said only the resistor have to be replaced since it did not harm the other components of the ecu.

...i'm going to have it installed this weekend and see if it works.

....if it doesn't.... i'll get a new engine, rather than paying over 50k for a new ecu unit...
