RS 1991 V6 - casual "check engine" (code 43, ESC or Knock sensor)
My check engine is sometime lightning up for a couple of minutes then turning of... The engine is running perfectly, no jerking, nothing...
The previous owner told me this often append to him if he did not use hi octane fuel (91+).
I just bough it and last thank was filled with 87 octane... Could it be the problem?
The car has also been stored for the whole winter, he has now 300km since the begining of summer.
what could be the problem?

I manage to figure out how my tech1 scan tool work and was able to get the error from the ECM: 43
It look's like it's related to the ESC 9Electronic spark control) or "Knock sensor".
I was also able to receive a signal from the "knock sensor" with the scan tool, because whend driving, the "knock retard" did change to a value and the "Knock signal" goes from "No" to "Yes"...
So, could it be the ESC?
Car is starting fine, engine running fine, but from time to time, the idle is not perfectly stable and sometime fluctuate between around 600 to 900 rpm...
