I got a 91 crx w/ DOHC ZC. Recently, after the car has been running at full temp for a few minutes, the temperature gauge needle starts to go crazy. It'll bob up and down sparatically, and also dip in direct relation to the gas pedal. I can stop at a red light and the needle will rise back to regular level, but once I hit the gas and start accelerating it'll drop down. I believe this is some kind of sensor problem or something. I know it's not the actual engine temp, my heater works, so I know the thermostat is working. The engine is operating normally too. So IDK, It's freaking weird . anyone seen anything like this or have an idea what it could be? Any help is much appreciated
