hi im newbie and own a 1995 e220 w124 saloon which we have owned frm new. well a problem has arisen that my car when driving wont accelerate hard anymore and it dies goin uphill it struggles going uphill and i need some help in finding out what happened to my beloved merc . shes only done 77000 miles and we love her to bits. can anyone help me with this issue please:wallbash:
 
air flow meter? , had plenty flat spots with mine till it was changed
 
Star on a 124 is very limited. Look for vacuum leaks and also there is a possibility that the cat is blocked.
 
Blocked fuel filter maybe? Has it ever been changed?
 
Is it misfiring= not running on all cylinders--- a sort of juddering sensation especially when putting the foot down? If so its probably one of the ignition coils or associated wiring.
 
Blocked fuel filter maybe? Has it ever been changed?

That was the exact cause of a similar problem on a 190E I bought as spare or repairs a while back. A new fuel filter, bottle of injection cleaner and a full service saw it fit for service.
 
well we had rac out and they did something near the throttle body and believe or not it got worse aaahhhhh! anyone know a good mb specialist in london !
 
They may have fiddled with the throttle cable which ends up at the throttle body linkage. Get someone to depress the throttle pedal and monitor what happens with the throttle linkage--- it should rotate thro 90 degrees to fully open the throttle plate. Things get more complicated if it has an electronic throttle [ possibly fitted with cruise control]
 
will look into that 2mrw thanx guys for all the input , really need to find a specialist in london and get it sorted
 
hi i`m a newbie here to this & i have read many posts & have used some of them to check my problem, but i still have problem. i have a merc 220E w124 111 engine & she is having probs with starting & when she does the idele is iregular at one stage she was jurking i did a reset which i found on 1 of the posts here & that helped. i have taking it to be put on that computre thing & it said she had a sorting on throttle body wire, i have cleaned the throttle body and checked the wiring inside it and its all new, which tells me that it`s be re-conditioned. i`ve had the car just over a year. can anyone tell me or give me a diagram of which wires go were inside the throttle body so i can check to see of mine are right. thank i in south africa guys

HERE'S A BASIC EXPLANATION. Browser Warning

Rewiring the Electronic Throttle Actuator in a W140 Mercedes
AND

Yet another ASR Problem; '94 S500 ***** THIS MAY NOT BE YOUR UNIT BUT WILL BE VERY SIMILAR! this is the only diagram I know of of the internal workings. The problem is that these are very complex electro mechanical units made to very accurate tolerances. There are mechanical gears/bearings and springs to wear but the most likely problem is with the sliding contact resistance surfaces These are unique to these units and not readily obtainable as spare parts--- for all these reasons its probably best to try to source a complete replacement or reconditioned unit with a warranty


and here's a few videos to help you will see how complicated a job it is!!!
