wionder if anyone here can help -my 2001 e55 has an intermittent problem -when cold, for the first couple of minutes, it's very jerky,and seems to hang on to the gears,under gentle acc. for too long. and then, every so often, it will do the same thing when warm -I had an LPG conversion done a year ago, and that's just been serviced and all is ok -i had this problem before,and the Merc agent changed the 02 sensor which seemed to cure it -they/ve just changed the MAF, but it's still there -naturally the local Merc. dealer. who I have no faith in anyway, is blaming the LPG conversion, but the garage who did the conversion, who are very reputable and have done three ML 55's with no problems, have agajn checked it and said there's no reason it's anything to do with the conversion.- no fault codes are showing on the diagnostic check, so the Merc dealer is of no help -I did think I had the faint smell of eggs last tine it happened, which could indicate the cats going, but i don't know if i imagined it-anybody here had the same problem or got any ideas? -I'm really struggling because Merc are not being at all helpful, and,whilst the LPG dealeres are quite willing to keep investigating, as are my own local garage(not the merc dealers)they are a bit stymied as the most obvious things, i.e the O2 sensor and the MAF have been changed-i'll replace the cats if i have to, but that;s a very expensive option if it's not the answer,
thanks for any help
