Problems after porting tb and adding new maf

Just added a ported maf which i have heard makes you run lean which would be good for me because of me running rich already. I checked with hp tuners and im now running in the 700's and 800's in the a/f ratio when it used to be mid 900's.

Here is the problem I took my camshaft out of the tb and must not have put it back right because it doesnt show on hp tuners that its changing.

It now idles much higher and w/o touching the gas I can get up to like 30. If im driving at 50 and take my foot off the pedal its keeps that speed...

I know the spring is pushing the blade closed because i checked it. Could all this be because of the throttle position sensor not working or something else.

Im about to take it all off now but I wanna get some advice because i dont think thats it.

Ill post my hptuners log so someone can check it out.

It says you have to log in to view those files. But yes, if you're TPS is reading above a certain voltage it will never go back to idle because it'll think you're holding the gas pedal down. Happened to me when I adjusted my tb set screw too far. I guess your tps is either fried or not turning with the throttle shaft.

Go to ripway.com and in the username, but charisma717171 and in the password put ilovetim , lol this is an account my girlfriend made earlier for me.

I think maybe I just didnt put the camshaft and tp switch back together right.
But would this also make it idle up to 30 if i give it no gas? I think I may have grinding away at the blade a bit much but you canonly see around it a little bit when you hold it to the light. I may have to buy another.

Well it looks like your TPS is working all right at least on the one from a stop, haven't looked at the other ones. You say you ground around the blade? That could be your problem, might not be getting a good seal.

One thing really concerns me about that log though, at WOT your bank 2 ltft is 10% and your bank 2 o2 is at 920 mv. But your bank 1 ltft is 0 and your bank 1 o2 is at ~700 mv.
