Same problem
I have the same problem and it's been driving me nuts. I replaced the spark plugs, cap, rotor, OVP, fuel distributor (had a couple of spares) and finally, the fuel filter. Had some improvements now reading this I have to go replace the fuel accumulator.maybe the fuel pump. Hopefully my catalytic converter is not clogged.
Vehicle- 190E 2.6 Sportline I replaced both fuel pumps and the fuel accumulator, The catalytic converter was good still the problem was there.....I replaced the fuel injectors and the car ran much better after that. |
Alright,
Got the new pumps, filter, and accumulator. Full Tank of Premium 93. Still has the same problem. It is so bad that it is undriveable. I did notice today when I drove it that the check engine light would come on and off when it was acting up. Anybody have any idea's? Could it be the CAT's? |
Did you replace the wire from the coil to the distributor cap? What type spark plugs did you install? Refer to the Owner's Manual for the correct non-resistor spark plug for your engine. You may want to confirm that the ignition wires are routed to the proper cylinder from the distributor cap. Note that Bosch distributor caps have each terminal marked with the corresponding cylinder.
I presume you installed a new fuel filter. |

Didn't you say that it still has periods where it runs fine? If the cats were plugged you wouldn't have that. Is the check engine light the only one that comes on? Does it start fairly easily or is it hard to start? Does it run hot and/or warm up quickly?

Have you checked operation of idle control valve? Could be possible the valve is stuck partially closed and won't open. Pull her off and shoot it with carb cleaner then give it some power and it should "click". If there is no click, then its dead.
The other culprit is the EHA. |

Yes it is the only one that comes on. It only flashes on when the car starts to what feels like miss bably. Bad enough that the only thing that will take care of it is to floor it to get it to accelerate. Starts fine. Warms up normally. Runs at normal temp too |

She idles with no issue's so I thought that wouldn't be a problem. Should it still be checked |
I thought that somebody would have an Idea. Why is everybody clueless.

It never runs fine just better than not running at all. It idles Fine, starts fine. Doesn't like to go if just bearly touching the gas. You have to floor it then it accelerates poorly |
When you pull the line that come from the bottom of the tank (with the gas cap off), does the gas gush out or dribble?
