Lightbulb My brother's 87 535is has the EXACT same symptoms

Did you find out what caused this??????.

The fuel pump, filter and regulator have been replaced with no results. This last weekend I replaced the MAF meter and the ICV. I was able to get the car to run again.

Symptoms. It will start cold and run perfectly with a smooth idle. As soon as it warms up the idle gets irratic and lumpy.

The other odd thing I notice is when I pull the throttle and hold it, the RPM's drop off and while holding it still they'll come back up. It acts like a fuel problem.

I would appreciate any advice..

Thanks
