manual says its a Electronic Spark Control issue? what does this mean?

runs ok/no light while moving but as soon as i have to stop at a red light/stop sign SES light comes on. while light is on, feels rather hesitant and sluggish. Buddy of mine said it could be the module in the distributor, anyone know name of the module?

if theres a thread for this subject already, please send link. i spent about 30 min looking for one and i didnt find anything lol

 

code 43 is knock sensor. test for power. got it? replace it.

 

thanks dude. i will be replacing it this weekend
