Throttle position sensor insufficiant ac?

I'm throwing a throttle position sensor insufficiant ac code. Has anyone seen this code before? It came up right after I did the heads and cam swap and I think it may be causing my tranny not to down shift. If anyone can give me info on this code it would be appreciated.

Thanks
Mike

I got the same thing after my trex + lsx90mm install. Im not sure if thats what causing the tranny shift problem or not. Does it seem to do it sometimes and other times it wont?

Yup! I'm going to try a different Tb and see if that fixes the problem. If I figure out whats causing it I'll let you know.

I guarantee that code will cause auto shifting issues. You need to bump up the range of the P0121 code's min and max MAP values with larger cams with less vacuum. I have only seen it come up with cams larger than a ~TR230.
