1994 e320 surges at idle but ok when driving?

Asked by May 26, 2016 at 02:48 PM about the 1994 Mercedes-Benz E-Class E 320 Convertible

Question type: Maintenance & Repair

At idle it started surging up and down but in gear
under load no problem?
Would rather not take it to a dealer to analyze. I was
told probably either air flow meter or dirty throttle
body?

Clean them and see if the surging goes away. Any lights lit up on the dash?

No lights on dash. Thanks

Have it scanned for DTC codes the computer knows! NO lights necessary it has codes. 22 years old a good through tune is needed.
