Engine power reduced

[Hableel]

Hi everyone, i have a problem where i really just cant figure out and it comes in annoying times.

my camaro 2010 ls3 gives me engine power reduced after i have left the gas paddle from flooring it, the car is not stock its a 500whp has basically all the bolt on's N/A, I've checked all the plugs but i had this ground wire that goes in the wire harness for the injectors and coils and its on the back of the engine next to the cylinder heads anyways so it was torn maybe by mistake by the guys at the garage but it was tightened and the problem is still there, every time i try i floor it and leave the rev go down by its self the car would give me engine power reduced.... so my question is anyone having the same problem and got it fixed? i will get the codes in a couple of days, but some have told me that i should change my stock coils and plugs should i do that?

im accepting annnnny suggestions so please help in anyone

I had the same thing happen to me yesterday i was driving on the highway and my car started to shake. Engine power is reduced was displayed along with the stabilitrak and cel. I removed both the maf and throttle body sensor and reconnected it. It took about 4 or 5 attempts to start the vehicle. I recently install an aftermarket throttle body and I thought I securely connected these 2 plugs but I guess the connection may have been lose. I used my Sct x4 tuner to read the codes:P0068,P0122,P0222,P0223,P2135.(All related to the throttle body and maf) I cleared the codes and so far shes starting up fine and no cel or engine power reduced. But then it is snowing here in Ohio so i cant really drive my camaro. Good luck!!! finding the codes would help alot.
