95 E 320 Benz

VEHICLE WAS RECENTLY TUNED UP 3 MONTHS AGO. NOW WHEN IT IDLES AT TIMES THE ENGINE WILL BEGIN TO RACE A LITTLE ,THE RPM GAUGE WILL GO UP AND THEN BACK DOWN TO A SMOOTH IDLE. I KEEP IT IDELING IT WILL BEGIN TO RACE ON ITS OWN AGAIN AND THEN GO BACK TO A SMOOTH IDLE. IT HAS RUN FINE SINCE THE TUNE UP AND I DIDNT HAVE THIS PROBLEM PRIOR TO THE TUNE UP ANY IDEAS THANKS

Dirt in the throttle body or IAC valve if so equipped.

Back to the shop that did the tuneup. First verify they didn't leave any lines off or move something. Barring that, have them clean out the throttle body.

Kill the caps, no need to shout.
