DML,
Installed the 180 thermostat today. Took it for a test run, and got one or
two pings with the engine not even up to its new operating temp. yet. Once it
warmed up to its new temp., experienced similar rapid pinging as yesterday,
but not quite as bad. Detonation occured around 4300 on first run, and about
3400 on second run.
Obviously I still have a problem. The only possible cause that I can think of
now is lack of fuel. I bought the truck used with 43,000 miles on it and now
it has about 73,000. My guess is that the fuel filter has never been changed.
I'll try this next.
