hey, ive been getting code 43 "43. Low voltage at electronic spark timing circuit" a couple weeks after i installed my headers, full exhaust, and full emmisions delete. i thought it would be the knock sensor so i changed it. the car was running ok for a couple hours, then when i romp on it the code tripped again, and im pretty sure the car retarded the timimng. after i installed the headers im pretty sure i damaged/burnt some spark plug wires. is it possible that damaged plug wires would trip #43? if not,,, WHAT AM I LEFT WITH HERE??? thanks.

its an lo3

 

I have the exact same situation, except I don't have headers, and I'm absolutly sure they're not touching the exhaust manifold...so I'm guessing that no, the wires don't ahve to do with it.

I could be wrong though.

I would like to know more about this too, its driving me nuts...especially sense it kinda surges sometimes trying to adjust the timing back to normal...oy.

 

My spark plug wires wern't burnt but very old and were around 3 ohms measured... should be around 14-15 ohms

that did trip code 43...

Hope this helps...

 

hmmness....
