Error Code: 43

I already replaced the rotor, the cap was still in good shape. Do I need to replace the distributor itself? I am still using my old wires, though I dont think this would cause an error that relates to the distributor.

Code 43 is Knock Sensor (KS) or Electronic Spark Control (ESC) circuit fault

I was reading in my Haynes and Chitlins(Chiltons) books and they describe the ESC as being part of the distributor. My dad told me he had a big issue with the ignition module on his fiero so I think I will start there. Autozone has a way of testing this module to see if its a problem child or not. I didnt think of the error code meaning a problem with the knock sensor, I will have to take a look into that one.

yeah i had the same problem i had to replace my knock sensor!

sweet, thanks yo.

KS error code could be Bad KS, Bad connection to ECM, Bad wire to ECM or Bad ECM

Hey, we had this one:

We ended up replacing the whole ignition system since it was tripping a few other codes. New cap/rotor/HEI module/& coil and we're back in business.

The 305 is still slow though :(

I sure I dont have to go that far.

Though I would like to replace my POS 3.1l v6 for a nice v8. Prolly go for a used 350 and have it rebuilt.
