Reduced Engine Power Help
So heres the background. My 07 ls2 had just a vararam and ran great. I had the TB ported. I reinstalled it and forgot to hook up the connector so the car idled rough and it kicked it in reduced engine power mode. I shut the car off, connect the tb and the car idled just fine in park for a few mins and then kicked back into reduced engine power and threw up 3 codes. p0122, p0223 and p2176. I've checked all the connections and nothing seems to fix it. Any suggestions on where to go next?

First DO NOT DRIVE THE CAR. Second, try clearing the codes twice in a row, if the problem persists then your throttle body is most likely damaged. If it has any mechanical resistance then the codes will come back.
Let me know how it goes.

I cant drive it. I have zero throttle response. Matt, i'm going to try to clear the codes twice and see what happens. I read somewhere that resetting the ecu might do the trick so i'll pull the negative terminal and try that as well.

Update.. so i disconnected the battery hoping to reset the computer. Well now the car wont turn over. It thinks it is on and the gauge panel still shows reduced enhine power. Now what?
