Hello;

Since i've purchased my diesel, my trusty w126 300se has been sitting for a few months. It seems to have developed a problem with stalling.

When starting up and on 'fast idle' it is fine. After driving for about 3-5 minutes, if I come to a stop it is ok, but when I accelerate, it stalls. I've checked other threads, and am more confused than before- is it a sensor thing? I've cleaned the MAF sensor, to no avail. I've put some injector cleaner through, nothing.

When the car is warmed up its fine, but still seems to idle a bit more roughly than it used to.

I'm wanting to sell the car, but need to get this sorted first. Its too nice of a car to sell with a problem.

Any ideas????

oh; by the way; I'm commuting 150 miles a day in my w124 250D and love it! Its cheaper to drive than a fiesta and so comfy.
