Nasty ping...need advice
The other day my 95 LT-1 has started to ping badly during acceleration. The water temp hasn't been sitting at 190 degrees like normal it rambles around more now and seems to climb quickly with engine load. Never got over 220 yet, but the weather is just warming up this week.
I monitored the PCM with PCMcomm and it say the engine is knocking lots (thousands of counts per throttle stab), the timing is being retarded when this happens.
Any ideas will be appreciated.

Check your fuel and maybe the knock senser
