Po 43

It says "electronic spark control failure".....

So i replaced the OPTI w/ an accel opti, Accel Wires, and TR55's, still threw code...
Replaced Coil w/ an MSD coil,... still threw the code....
Then replaced the Knock Sensor, Knock Module (both with LT4 ks, & km)... Is till throwing a damn code! WTF!

Code 43 is Knock Sensor (KS) Circuit - it's reading incorrect voltage on the circuit. Don't know the procedure but sure there's a way to check it. Someone will chime in...
