97 Reduced Power HELP!

I was reading through the other posts and was hoping someone could steer me in the right direction. I'm having the same problem as some of you with the reduced engine power. Here are the codes:
P1221, P1416, P1571, C1278, C1281 and B0432
I have a list of what each of these codes means, but this doesn't tell me much.
I also read on another forum that I might need to have the computer re-flashed.
Any help would be greatly appreciated.

If you havent already done so just disconnect the battery for a while and try it again. It seems to have worked in previous posts.

Thanks, I'll give it a try. I'm bummed! This is my first sports car and I haven't been able to drive it for weeks. Although when it was running fine, it was unbelievable!

The same happened to me and all I did was disconnect the battery and wait five minutes ot connect it again It has been fine for the past 3 months.

Goood luck!
