Check Engine Light
OK, I give up. First the speedo starts acting flaky, now the check engine light comes on. I disconnected the battery a week ago when it first came on, and it was out for seven days. This morning, it came on again. Is there anyway to pull the code(s) without a scanner? BTW, this all started when I hit 100K.
Thanks for any and all advice.

Ok, got the code. P0125, coolant temp no high enough to enter closed loop operation. Low coolant, bad thermostat? Truck has always run cool in the colder weather, but it has great heat. Suggestions?
