Advice please
Coding says general engine misfire.
2 plugs burnt out 1 and 4 on RH bank but misfiring both banks?
Supercharger fitted.
Done 14k miles.
Replaced plugs and still running like a bag of spanners.
Sounds terrible so it's been sat up for months trying to get fixed.
Last ditched attempt please before it starts causing big bills!

 

id change all the plugs in it not just the failed ones, if you havent already. check compression in all of the cylinders as well. check fuel delivery, you have enough air with the super charger. might be worth checking the timing as well possibly if you can get it running long enough to get it on a OBDII reader cheap or buy your own.

replace wires and coil packs as well, imo. if you have good spark in all cylinders, gas, and compression, theres not much else to have LOL

I am assuming you have ran 14,000 km's with the supercharger? Correct?

If so, I would look towards the following:

Clogged injector, bad ignition module or coil packs.

If it's running now, check for a vacuum leak at the manifold. To test you can use a can or carb and choke cleaner or the like, just be careful around the coil packs.

Check fuel pressure and if you have the ability check your timing and pull some out.

You said "spanners" do you live in Europe, may be the UK by any chance?
