Alright, im new to this site, i currently own a series 2 rs turbo, but im having a few issues at the moment and wonder if i could have some advice,

when drivin once warmed up the engine cuts out? Also im getting alot of backfire n no boost what so ever! But it only happens everynow and then, but its not smoking (it does when backfire), ive bin told the coil could be on its last legs? have just replace spark plugs and doene a service to help to see if it would solve the problem but made no difference.

Im jus really puzzled lol

Thanks

if i remember there is a cold start valve on the back of the manifold,this may be sticking causing overfueling when warm, to check unplug the valve and try a test drive.
