Maybe the O2 sensor or a fuel pressure issue. You could try removing the plugs to the coils one at a time and see if there is one that makes little or no difference. Have you cleaned the throttle body?

Use your xcal and read the codes and list them up

I doubt it would be plugs and coils, generally they will fail under load. Id nearly bet you will have codes P1270, P2110 P2105 or something along those lines.

You will have a either faulty tps, dirty throttle body or vacuum leaks or a combination of those.

Less likely than that will failure of the throttle body motor itself which isnt as common but does happen. Its only a tiny little motor.

Post of the codes and we can help more

Sorry mate I missed your reply, Im not on this forum that much, Im mainly on the other one haha but sshhh!!

Mate just hook your xcal up to the datalink port in the fuse panel, the xcal will power up, the scroll throw until you see read/clear dtcs and hit enter, then follow the prompts it will tell you to turn ignition to on then it will do the test automatically, Then it will show all the codes, write them all down and post them up.

You wont reset anything so dont stress,
