My 1996 w140 issues inquiry's welcome
Well to break it down here's everything I've found wrong with my recent purchase so far. Top of the list is definitely this bucking/ horrible idle it's recently started doing and it's slowly gotten worse because it's starting to die if you leave it in park. I am currently getting a code for P0410 it comes back secondary induction system if anyone could help on that it it would be awesome. I'm planning on doing the normal check MAF, plugs, wires and vacuum if there's anything specific someone can pint me towards there it would really help. Also planning on cleaning the throttle body as well. Besides that it is all somewhat little things, like the gauge cluster seems to be a little dim and the light around the seat adjustment on the passenger side is out blah it would be helpful of someone could tell me which bulb is the fog light before I tear into it. The soft close is a little iffy all around I've read through the forums and queried a couple and well to be honest haven't figured it out yet Im guessing a it's the pump because that's basically the last thing left. Sadly with all of these issues I have indeed fallen in love with this car going from my Cadillac to this I dodnt think there would be to much of a change and it was I loved my Cadillac but I've fallen for this car. If anyone could help on the issues that would be awesome. I'm not car illiterate it's just when I get a car I've never had my hands on let alone a make and model I've never had my hands I just like to know everything I can and get as much help before I f something up and yes I'm a stubborn person and like doing my own work gives me more of a connection with the car

what engine,p0410 is mostly the hard vacumm lines are broke.I use standard rubber vac lines to replace.To check MAF dissconnect it from air cleaner,start engine,blow into Maf,if engine changes,its working.Try pulling fuses to soft close pump.Fuse in trunk.Sometimes pump will time out if something caught in door.
www.benzworld.org,the w140 section is a good place for help.ps I'm not in a smog state so I disconnected my secondary air injection.So the car has run fine for 5 years

That would be the 4.2 I'll check the vacuum lines and the MAF tomorrow when I got some day light and get back to you on this so I can hopefully close the threads out or ask more questions and thanks old sinner you've been a lot of help so far

as I said before mines doing that crap under load since June,replaced everything except crank sensor and cam sensor.They are on order.If they fail to fix car its going to a MB garage,not the stealership.

Hey,
I don't think its any of those,
my mind is telling me one of the below
1 fuel pump
2 fuel pressure control
3 any leak in the fuel lines or in the fuel tank cup no matter how tiny leak it is
the basic fuel system depends on pressure
I'll let you know if I get any updates
good luck
