Pinging & Overheating

Pinging & Overheating
I have a 96 SE. I purchased it brand new. I have no engine modifications. I have always taken it on long trips without a problem. But recently, I have had a problem with pinging and overheating. When I am going up a hill with the pedal floored, the engine begins to ping and the temprature gauage starts to go up. This is with the A/C on or off. I have to turn on the heater to reduce the temprature. Can anyone direct me as to what the problem is.

What is the mileage on your car and what is the maintenance you have done on it and at what mileage.

MAF sensor could be on it's way out too. Or dirty fuel injectors causing a lean condition. But your cooling system should be able to keep the engine cool still.
Have you maintained your cooling system? If your cooling system has corrosion in the radiator, it will not properly dissapate heat. You will need to have an acid bath done to clean it out. Only a radiator shop can do that the right way. I don't think your thermostat is sticking, it's design is such that when the spring gets weak, the fluid flow path opens it up early and your car runs cold.

I pulled ECU codes and there was nothing to report. I have changed the fuel filter and have changed the radiator fluid several times. I sometimes hear a small ping when shifting from first to second. That happens no matter what time of day or what temprature it is.
