okay i got this code today. And I noticed when my car warms up the tach needle will start twitching but there is no really difference in engine rpm. Then wait and it will start surging on its own. like as if i am pushing on the pedal. I found any problem like that is related to the Icm. And now I found that I got dtc 41 code.

igntion control (IC) circuit ( open or shorted circuit )

Now this is what i am wondering is this code directly related to the ICM/ coil or can it be the opti too. I just put on a accel opti here in january 2007.


thanks
