vauxall corsa 1.2

[rylands]

my car has trouble starting in a morning,its like it needs to warm up. A yellow warning engine light comes on , on the dashboard every so often and even when my foot is on the floor it still goes slow & chudders then syddenly picksup speed on its own even when on the moterway it slows up & down by its self its quite worrying when in a lot of traffic as it looks like im breaking down. Then off it suddenly goes again & the the engine warning light goes off. Im off on a long journey soon so would appreciate some help.

You'll have to take it to a garage and get the fault code read - the warning light is for the engine management system indicating there is a fault - could be a loose wire or a faulty sensor - gettting the fault diagnosed with the right equipment is the thing to do.

Air flow sensors are a common problem on corsa's especially the 1L. this can create the this problem.
