W124, New Parts Kits and Manuals

Recently,

My car has been acting funny. It will only start if I give it gas and it won't idle to save it's life, I have to keep my foot on the gas at stop lights.

I replaced the stock fuel filter, air filter etc. I've read that it could be the ovp, but the socket is empty in my fuse box and I can't find anything that resembles it anywhere else. My dash lights (Brake warning etc) do come on at idle until I give it some gas.

Any suggestions would be appreciated.
