1990 240DL, 185,000 miles. Replaced all tune up parts including plug
wires, back fire valve, fuel filter, and just replaced the air mass
meter with
two different used ones bought off of the internet. No computer
readings. No apparant air leaks. Two mechanics haven't figured it out.

What could cause these symptoms: Car is stalling at idle and initial
acceleration. Car runs fine when cold but after it gets hot (about 10
minutes) it
stalls at idle and upon acceleration from idle.

Where else should I look?
Thanks for any help you can give.

Exhaust valve clearance; Valve clearance closes up when warm. do a
compression test.

Check the thermastat in the air cleaner box. Cured same problem on my 84 240.
