Hello and Welcome..

My name is MIKE - Im happy to help you..

I need to ask you a couple of things first --

What is the mileage on the car?

What is its general service / recent repair history?

Do you have any fault lights on , on the dash?

Do you have any fault codes for this fault - if so, what exactly are they?

Is this a definate "misfire" - have you determined that ? If so - on which cylinder / s ?

When you say the ECU is ok - tested ok - how exactly has that been tested?

The coil pack you say is 6 months old - did you have the same issues before - when you replaced the coil ? Also - was that replacement coil a genuine Vauxhall - and a "new" one?

Is this a "dual fuel" car or just petrol ?

Last - have you carried out any other checks / tests of any type / replaced any other parts?..

The more you can tell me , the better I can help you - to inc the answers to the above especially -

Kind Rgds, MIKE...................................
