2000 Honda Civic Operating Temperature Issue
Hi everyone,
I have been having an issue with my car recently. Out of nowhere it stopped reaching ideal operating temperature no matter how long I leave it to warmup. Once it does somewhat warm up as soon as I'm driving the operating temperature drops significantly. The car will also struggle to accelerate after idling at a red light. The exhaust pipe also smells like it is running rich. We just changed the thermostat thinking that it might fix the issue and we've also changed the coolant temperature sensor but neither of those fixed the issue. Are there any suggestions as to what may be causing this issue. Thanks!
