Last week my timing belt had snapped resulting in 5 bent valves after it snapped doing 40mph

now after some help from a friend i was able to get the valves and head done by a professional shop/garage and got it back the same day and rebuilt the engine back up to find it wouldn't start. Then realised we had set the timing 1 tooth out so fixed that problem and car started first time but with a judder and splutter

now after driving theres not much power when put foot down. when cold it splutters judders and wants to die. once warm theres no power and it judders slightly when idling.
error codes where throttle /pedal sensor. and a 1157 code ( fuel?? )
i have tried everything except a new engine.
Heres everything have tried
second hand throttle body
second hand throttle pedal x2
deleted plug behind glove box
brand new could pack
brand new plugs
all new air intake pipes
map sensor
only thing i haven't tried is a lambda sensor but have one on the way from ebay.
Any help guys and gals please as i am about to scrap this C3 and be happy watching the crushing machine squash it into a small block of metal if it doesn't get sorted soon

P.S. Have read as much as i can find and almost everything points to the pedal, throttle body and ply behind glove box.
