Stupid Thermostat Question 200

Put a 92 B230 in my 91. Got a minor spark knock and have done everything to get rid of it - new vacuum lines, new knock sensor, cooler plugs, new cap and rotor, etc. All seemed to help a little. Red line treatment goes in next.

Just thinking - I put in an 87 degree thermostat. Runs slightly warmer than it did (guage is accurate as I put in a bypass kit long ago). Nowhere near running hot.

Any chance a slightly warmer thermostat could cause minor spark knock?

Thanks guys.
