Nothing like stressing out about everything that needs to get done in the next couple days when suddenly the CEL pops on.

The code reader shows P0128 so I will check (& probably replace) the coolant thermostat as suggested in other threads. But it also shows P0128pd and MIL ON with 0 incomplete monitors and 7 ready (Misfire, Fuel, Comp, Catlyst, Evap, 02 Snsr, and O2 Htr) - so I am wondering how much I need to be concerned about the monitors?

FWIW I just recently replaced the rear valve cover and solved a longstanding high speed oil consumption issue, so I wouldn't be at all surprised if the emissions are a bit jacked up. Can't really afford to throw a bunch of money at the car just now though so I want to be sure whether I actually have a problem first.

Thanks!

Do not worry about the monitors. About a decade ago I went with a low-temp TRD Thermostat, 170 degree combined with a Tom's High Pressure Radiator Cap. I also with coolant throw a bottle of water wetter in there.
