Code 15....

Well I got my car running, looks like it was my coil...bad news I am getting a code 15 now. 15 Coolant sensor - low temperature fault
So what does that mean? Do I need to change out my Coolant temp sensor now on my manifold? *** dang this car is full of surprises. After i burned all the soot off the plugs i checked my fuel pressure, i am running about 15psi for TBI vehicle which stock is 9-10psi. I uped it though but i don't think thats to bad. I wouldn't want to go any furthur. Anyways how much to CTS cost usually?

Yup, it get rid of my code 15 and now all I have to do is lean my car out (plugs were black) and everything should be back to normal.

Well i got it from 16psi to 14 psi, but it seems no matter how many times i turn the damn adjustable fuel pressure regulator it only decreases a little bit. Any thoughts on that? Anyways, we will see what this does.
