My corsa is jerking and feels sluggish when driving. No management light on but feels if no power. As if air is been sucked in and you have that lack of power but jerks also. Doing my head in. Iv noticed a nipple on a pipe near gear box at bottom, as if it had a pipe pushed on a size of a small thin pipe, will that be the problem sucking air in.

Had a few of these like this, no fault codes registered, each time it was the turbo waste gate seized,accessed from the top down through the exhaust manifold with a long lever,get it moving back and forth against the spring and give it a spray with copaslip/anti seize grease,symptoms are an intermittent lack of power, hope this helps,good luck
