So it's a standard car with twin coils and it's misfiring and spluttering under acceleration, popping back through the exhaust. Replaced inlet gaskets, plugs, checked and cleaned the gearbox pick up, no obvious air leaks, vacuum pipe to ecu is working, all earths are good and now i'm at my witts end

It was running iffy before xmas and it turned out to be the inley gaskets, changed these and she was running well until recently

If you hold the revs @ 2500 rpm it's misses like the timing is out if that makes sense and it seems to be running rich

Can anyone shed any light on what to check pls
