Throttle reading incorrect on AFC

[Shogun]

Hello all,
haven't been on the forums for while and didn't drive the car for a few months because of this problem.

I have the afc-2 but the throttle reading it shows is not correct. At idle, it should read 0% but mine fluctuates all over. It's never stable at one reading.
Under load its the same thing.

I bought a new tps, adjusted it properly. no change
changed the wiring from tps to ecu harness (new tps harness as well) but no change.

Car is now throwing code 22, but that seems to be totally unrelated to this problem.

Any ideas?
Need help or the car will sit in the back yard and rot.

Thanks in advance for any help.

hey make sure you have it hooked up to the right signal...ill bet its hooked up to the injector pulse signal and not the throttle signal... i did that too

Ideal,
I checked it several months ago and also had the shop re check it (they did the install)...but I'll look at it again this weekend.

Thanks.

any other ideas?

could it be the ecu?

I second what Ideal said, that sounds like the most likely option
