last week I started getting a code 7, my tps sensor. Luckily I got my str throttle body back so I was able to put that on and my backup tps sensor. everything was running fine and then about a day later I went to pass someone so I downshifted and then floored the car at about 70 m.p.h. I saw my check engine light come on.
Now the check engine light comes on when I floor it usually when I hit third gear.
Can someone please tell me what they think might be the cause of this.

thanks
