Flashing Check Engine Light!!!

What does this mean? When I start my car up, about 20 seconds later the check engine light flashes and the car rev's up to like 2000, if I start driving it, it drops down back to normal. Happens most of the time I start the car and I had the codes read... I just changed the CAM sensor and it fixed some of the problems but I still have that problem.

Also I changed BOTH O2 sensors yet I got codes....

anyone , im pretty close to mechanic time, I have no idea what to do.

Should I replace the EEC ?

Have you disconnected the battery to clear out any stored codes???

yes twice, I really dont know what else to do.... I cant use a EEC from a 93 tbird auto in my 92 tbird SC manual right? Do you think its the EEC?

I know in OBD2 cars 98 and up, flashing CEL are really bad like misfiring and running super rich but my car is doing neither... I think it is running rich but not crazy rich.

That's a lot of codes to be getting at one time. I'm no expert by far, but seems like you either have a lot of bad things happening to it or the computer may be at fault. Do you have one you can change out with it to check?
