Diagnostic Help Required - 92 500E

I have a 500E with 135,000 miles. Recently the idle quality has deteriorated and vehicle surges when coming to a stop. Under full throttle acceleration engine runs strong but also has surging at higher RPM's.

I replaced caps and rotors 500 miles ago. No change to symptoms.

Anyone have any ideas?
