1995 E300D Surging Question

The car is starting to surge on a regular basis. Let me describe the situation....

When I first start the car there is a bit of surging at idle, but this goes away fairly soon after started (assuming some air getting in, but it will start without fail regardless of the physical position of the vehicle, such as pointed up or down, etc.).

The real issue is that if I'm driving at approx 45mph steady, after leaving the home in the a.m., the car will surge fairly aggressively. I can press the peddle just slightly and it goes away...without fail. Then at approx 55-60mph it will do the same thing. The car has 304k miles. It's almost a guarantee that the car will perform in this manner. The issue happens 98% of the time at those speeds.

My thought is that the IP is going out.

Thoughts?

Thanks much!

Andy
