What do these codes mean? I don't have my shop manual at hand right now, so ur help will be appreciated!! Thanks
 
How is the car running.

67 neutral drive switch open.

77 Wide open throttle body not sensed.

From the way it reads you are running cool and need to floor it. What is the car doing is it starting. Is there a CEL on?
 
Yeah it starts fine and runs fine also, and no CEL. I just don't think my low speed on the fan is working, 'cause it used to come on at around the O on the temp gauge and now the gauge goes all the way to M or A before the fan comes on. Or, maybe I just can't hear it, and my problem could be leak:confused: . I don't know, but I'll get it on the lift today and I'll see what i can find.
Thanks for the code meanings:D
