This just happened to me. 2001 ml320, 38k miles. dealer said I got some bad gas and the fuel line was flushed. The diagnostics plus the cleaning was $400. Then is started happening a week later - worse. Check engine light on, running very rough, pressing gas pedal to floor - not getting acceleration. Dealer then said some of the cylinders were gone and replaced the wiring, etc... another $500. Runs perfectly now.

Could it be that the computer put the car in LIMP HOME MODE?

I have had this problem with my 99 ML320 for six months. The problem is, everyone wants to fix it differently. One shop wanted to replace the ignition cables. Another wanted to replace the o2 sensor (these have never worked for long). Mt "check engine"light has been on for seven years. My oil light has been on for two years. The dealership told me to buy a new car six months ago... that it wouldn't run another week. I put 15,000 miles on it since then (currently at 215,000).

The fuel injector comment makes sense - especially since restarting the engine makes the problem go away. If anyone has any other thoughts I would appreciate hearing them.

PS - I am told every week that I purchased the worst Mercedes ever built. Have any of you heard this? The problems have been a pain, but 215,000 miles for $39k isn't bad.

How much should it cost to replace a bad fuel injector?

Thanks, Sleepwalker!
I have a similar misfire lost of power problem with my ML320-1999 but no check engine light. It happened 4 times over the past 8 months but last month I have the same problem almost every morning, motor runing on 4-5 cilinders during warm up and I have to turn engine off and on again to solve problem. Yesterday, I added a Fuel injector cleaner Gumout and today verything is normal. Do you think that a professional injector cleaning will solve problem? Do you recommend to replace all fuel injectors? Is there a problem in to use Gumout for 2 -3 tanks to try to clean injectors?
We will appreciate your comments.
