O.K. Jeff K told me about the Tech Article on checking codes. I DID IT RIGHT THIS TIME!!!
KOEO, 11,28
Continuous Memory, 63
KOER, (tried this one a few times),24,28,63,76, 25 for the knock sensor.
Later as I went to double check the codes I got the following
KOEO, 11
CM, 63
KOER,63, and the 25 for the knock sensor.
Is it safe to say that the TPS is faulty? what about the other codes?

You probably just have to adjust it. There is a link in the tech articles on how to adjust it. I found it easier to take the IAC off and then try to adjust it. Mine was way out of wack and it idled 10 times better when it was right.

KOER 76: Insufficient change in VAF voltage seen during WOT goose. Either you didnt gose it enough (WOT to 4000 RPM or so), or you have a VAF problem.

CM 63: could be a bad TPS, but you should measure TPS voltage while opening / closing throttle a bunch of times to look for voltage drop outs, as well as inspect TPS connector and wiring before buying a new TPS.

28: was outside air temp under 50 deg F? If so, this code is normal.
