Hey guys I'm new here and have a issue I canT solve myself I own a 2000 grand prix gt 3.8 non supercharged and I recently have done the LIM gaskets and the upper as well and new o rings on the injectors I also replaced the coolant temp sensor and the thermostat and I have done and oil change and flushed the coolant and bled the system several times but I keep having an issue with overheating When I'm driving the temp Gauge stay at the half way point but when I'm not moving and just idling the car get very hot almost into the red. And the fans don't turn I have checked all the relays and fuses the fans will turn on about 10 min after turning the ac on but thats about it but the thing is I hooked a good scanner to my car and the PCM says my temp is normal it stays steady at 90 degrees celsius while the temp gauge at the same time says I'm almost in the red so about 120 Celsius so I would like some advice as to what might be my problem with the gauge all the wires look good and it used to work fine before I did the LIM
