Astra 1.6 twinport - 1.6 astra engine management light come on - Rich212121

Hey guys,

I have a misfiring astra. Had coil pack done and Sparks was fine for 3 months now same issue.

BUT it' not all the time.

It runs fine until I get to a bump road and after that my engine managemet light flashes and lose of power. Go still goes.

But when I use it again it's fine.

It' seem only when I hit a bump road.

Anyone else had this or know of it?

I was going to change the EGR valve as it maybe blocked or loose.

Any help would be great

Is the coil pack a genuine Vauxhall part or one of those cheapie chappie parts?

Hi

It's a genuine vauxhall part not a cheap one

Remove the multi-pin connector from the coil pack and very carefully tighten the pins on the harness wiring.(female)
