Had SES light come on....... P0128
DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
Do I need to put my 195 back in? I am running a non-Intense drilled 180*. Or an ECT sensor? It was mid-40s when I started driving this morning. Didnt really give it a good warm up, maybe a few more minutes in the morning now since Fall has finally hit in No. IL.? I think Im gonna plug up the fresh air scoop that I have for the CAI for the winter, also.
