my engine managment light keeps on coming on my 1998 vectra?
my engine managment kight keeps on coming on ,and at the same time it loses power and jerks,then the power comes back but the light stays on what is causing this
I think you need to get your fault codes read to identify the problem. Otherwise you could spend money replacing parts unnecessarily. Could be a coil pack on the way out but daz71's comments are valid too.

The cause is a faulty sensor on the engine probably a faulty map sensor or a crankshaft sensor(both common on Vauxhalls) but to find out a diagnostic code reader needs to be plugged in to the car. The light stays on because a fault code is stored in the ecu(the cars brain).
