Code 43

Check engine light comes on intermittently. Code reader say it is a code 43.

This is on a 92 Firebird 3.1

How difficult will troubleshooting be on this one?

Re: Code 43

Not very. It's one of 4 things. Knock sensor by the starter is bad (blue wire, white round plug), ECM is bad, MEMCAL is bad, or the wire between the sensor and the ECM is bad. There is no knock module on the 3.1.
