I just bought a Mercedes 190E 2.6. In the mornings when it's cold it takes a few minutes of cranking and playing with the gas before it will finally sputter and kick up to where it will idle.
What I have to do to start it is crank the engine and slightly tap the gas. Once it kicks like it's going to start I have to immediatly let off the gas. Then it will accelerate a little more. If I keep my foot off the gas it will die out, so I have to lightly hit the gas again and then let off again. Keep in mind that it accelerates when I'm letting off the gas. It's like it's killing the engine when I push down on the gas and accelerating when I let off. But I need to push on the gas to give the engine some fuel.
So I need to pump-release-pump-release to get it going. After it warms up a little it runs fine, and once it's warm it starts fine.
Does anyone know what could be causing this problem?
Thanks.
