1.8 turbo misfiring when cold
 

Hi my 1.8 turbo is running on 3 cylinders for about a minute when the car has been stood for a few week it doesn't happen when I'm using the car every day you can smell unburnt fuel from the exhaust I was thinking a plug fouling or a dodgy coil/ lead
Thanks

Pound to a penny its the inlet manifold gasket dribbling coolant into the manifold. Seals up when the engine warms up, misfire stops when the leaked coolant burns off.

Ok thanks will get it changed does anyone have the updated manifold gasket fitted to their cars does it leak like the original thanks

I have had the updated IM gasket fitted - over 3 years ago and no issues to date -also changed over to blue coolant ( but who knows):shrug:

Slap an alloy inlet manifold on, It'll never leak again:cool: Also gap the plugs to .75 or .8mm;):D https://i.imgur.com/b5tMBYcl.jpg

Thanks will order uprated gasket from rimmers it leaks water aswell so it probably will be manifold gasket will update when I've fitted it
Many thanks

I have done that as well :}

Ive put a new uprated viton inlet manifold gasket and new radiator cap on will see how it goes
