1990 No Up Hill Power? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I soldered in the new knock sensor plug and took the truck for a test ride.It feels like it is getting better but still has a low end miss that clears up as the RPM increases.
On initial turning on of the key the service engine soon light comes on for a short period then goes off.When I am driving it the only light that comes on is the shift light.
I ran the codes and only get code 12
It started raining but when it stops I'll do the thermostat.
