I have a '94 coupe. The other night I was driving through a school zone at 25-28 mph in 3rd. I got a slight hesitation, it has happened twice since, and the check engine light came on. I read the ECM codes and got a C12 and a H48. I have no manual to show what these mean. Can anyone help?

go to the C4 forum and check out the sticky related to codes. There is a complete listing there.
