Default Code 43

Every once in a while I'll get a softcode 43 and the car will start acting up not wanting to idle. The fault will go away and everything works fine again. I've replaced the module, sensor, and ECM. No luck! Could the problem be in the ignition circuit?

Has this happened to you? What was the fix?

Chek the knock sensor and the wiring going to it. Do you have an exhaust leak? Could be miss reading.
