Default Code 43 and 52 Help, Please ! 90 model L98

Hi Guys

I have the light SES switched on permanently by driving for the first time.
I followed the method to find the codes and Here they are:
43 : Electronic Spark Control
52 : Fuel Calpak Missing

I have verified connectors and open ECM for look the calpak is fixed OK and put sillicon but I always have the problem.
Besides, my C4 lost of its power, that feels easily. She's in limp mode in fact...
Thank you for your help

Patrick

Did you replace the knock sensor or tested it at least?
A bad sensor could have taken out the ECM or less likely the memcals knock sensor circuit board.
If you don't have anybody in your neighborhood with a 90 or 91, you could mail me your memcal and I could check if the problem travels and shows up in my Vette as well.
