I've got a 1990 164 which seems to be pinging on acceleration when hot.
After I start in the morning it's fine, but by the time I reach the
freeway it's at around 85C, and starts to ping when I accelerate in
either 4th or 5th.

I too have the same problem with my 91 164 so if there are any ideas out
there include me in too. I have posted the same question a while back but I
got no replies. It is now cold here in Minnesota so the problem is gone
since the engine never gets hot (above 175) but spring is around the corner.
