Car going flat and holding back

[matty85]

After fixing my car today went for a blast and all was fine but a couple times i would have foot to the floor then it would just seem like i had no petrol. If i lifted off it would go fine again. I have 3 codes that have come up...

1, 16955/PO571 Cruise brake switch (A) Circuit Malfunction
2, 17840/P1432 Sec.Air Inj.Valve Open
3, 17695/P1287 Turbo Bypass Valve Open

Also had these before i wiped it

4, 16795/PO411 Sec.Air Inj.sys Incorrect flow detected
5, 17704/P1296 cooling system malfunction

I have sorted number 1 well will tomorrow once it arrives
any idea on what the problem could be??
