Hi guys,

I have a 190e 2.3 16v and I was mucking around with the air/fuel mixture screw and now the car won't start, actually it starts then enigne dies instantly. Today I got someone to crank the engine and the engine stay running when i depress the air sensor plate a little. As soon as I release the plate it dies. Its extremely frustrating. I have no idea if its too lean or too rich. I've learnt my lesson, I won't muck around with things I have no idea about.

Thanks
