Ok guys i have a 2000 LS1 Swaped in to my 72 Nova and its been running GREAT for the Last couple of days and now sometimes i get a Code that says

0352 Ingition Coil B Primary/Secondary Circuit

0358 Ingition Coil H Primary/Secondary Circuit

These codes just come on when you drive the car HARD and then after that is starts Missing but you can Stop and reset the Computer and it stops Missing and runs GREAT but as soon as you Stand on it Hard the Codes come Back on not sure Whats up do i have a Bad Coil?

All so my Harness came Wired for 2 fans but i am only running 1 fan and it keeps giving me a 0481 Fan 2 Control Circuit Code How can i keep it from giving me this Code can i just Ground that wire so it think its Grounding a Relay when its just realy grounding to the Body?

THANKS for any Help guys.

 

Swap the #2 and # 8 coils with other cylinders and see if the codes follow the coils. The fan code just needs to be tuned out.

 

Ok THANKS i will try moving the coils and see what happens then. I guess i will send my ECM back to PSI and have them turn off the #2 fan THANKS.
