Thanks for the suggestion! But somehow, the car suddenly began starting ok again, even though I have to push the accelerator the first couple of seconds to prevent it from stalling. But now I am bact to my "old" problem. With a cold engine, the rpm are held at about 1000 rpm (due to the idle control valve, I guess). But after just a minute or so, the idle speed drops quite fast to about 700 rpm, like the valve is closing, and the engine runs quite poorly for a while, until it warms up. How long should the idle control valve work when the outside temperature is about 0 C ?
