A newbie here...so I will try to make this easy!

I have a 1995 E320 that idles, drives, and runs perfect. However, whever I decide I want to accelerate quickly it hesitates and sputters. Again...driving at consistant speeds it runs like a dream, and idles so quiet you can't even tell if it's running!

The problem started out a year or so ago when I noticed it would hesitate here and there during quicker accelerations. Now...if I get into the gas even a little bit it seems to briefly hesitate on and off until my acceleration stops and the car is running at a consistant speed.

Can anyone help here? Spark plugs? Fuel injectors? Any other ideas?

Thanks!
