This Vauxhall Corsa came into us with a report from a breakdown company that the catalytic converter had collapsed blocking the exhaust making it a non start. We quickly determined that the Cat was infact fine and not the cause. On trying to start the car it would run but backfire and would not rev correctly.
Next we removed the inlet manifold and on removal we found that the lower part had infact blow off. On speaking to the customer they reported that the car did make a loud bang before it would not start again.
Manifold split in half!
After sourcing a new inlet manifold we fitted it and cleared all the ecu codes and the car ran as it should leaving a happy customer.
