P-7100 surge at idle

I just got a call from a friend with a early 98 truck with a surging idle.
I have not seen the truck, but here is the problem.

Sometimes at idle in gear -auto- it will go rump-rump until either the throttle is touched or it is put in neutral.
What do we look for?
Is this a pump issue?
