E 65 in Sleep Mode

[eyes]

Bought a E65 few months ago its a W210 with a brabus 6.5 engine 450hp it drove like a beast touch the pedal and wheels start spinning but lately its sluggish need to press firmly to make the wheels spin got it checked nothing significant came up, one more thing Idle is rough put it in D and car is smooth again changed the spark plugs/caps also inlet manifold bushes and injector O Rings as mechanic thought there might be a vacuum leak no real change its frustrating to keep changing things without benifit so question is what next.

Best bet would be to get your MAS Airflow sensor checked (only replace if you have to since they are not cheap)

BTW - Congrats on "the beast"

hey i have a e320 and even though you buy the top gas sometimes at gas stations they cheat you and give you regular. you can go 2 different gas stations or get octain booster.

I had the same problem and it was the typical Air Mass meter. You can get them on ebay for much cheaper. I paid $150 for mine. Trust me it is not a waste because you could sell it quickly if needed, but you might as well keep it because these cars love to east Air Mass Meters.
Good luck and I love the Horse power or your Brabus Benz
