I asked a lot of questions before this year about getting it running right, but before getting it right the radiator gave up the battle and then it was summer holliday which I spent on an island of The Netherlands, so didn't touch the RS.

When I got home I spend another 2 months before I finally got a new radiator, and it's crap quality so this won't hold for long too
The old rad broke down because I didn't mount it on rubber again after fitting the cos intercooler, so I had to mount it on rubber now and reroute the hoses.
Therefore I needed an 90 degree bent with a diameter off 60mm.
Well, before that was in house I was another month further

Getting sick of everything taking so long, the hose finally arrived today, so I fitted it all up and tried to start the car.... Nothing!!!
I then called my mother for her to push down the air flow sensor, and it fired up, heavily overflooding, black plums on the exhaust, so I kept it at 3000 rpm for a while where it sounded quite good, but as soon as I got under 3000 rpm it was overflooding again.
In the meantime my mother was in the house again, so I had to get to the engine bay without letting the engine stall, well, I didn't succeed in that.

After that, no mather what I did or didn't do, it would fire up.
Another detail, before it ran, the sparkplugs were brown, like they should, and after running, they were pure black, so the engine did overflood, that for sure.

I hope we'll find out now what's wrong, please help!!
