Hello:

I recently purchased a 1986 190E as a project car. The car idles ok, but when you push on the accelerator the car wants to die. I have checked the following things so far.

The car has new plugs that are gapped to 0.032
New Bosh copper wires were installed.
Compression test on cylinders are 125,125,125,120
During idle if I pull wires 1 & 4 the engine starts to die, but when I pull 2&3 there is no difference (there is spark to plugs 2&3).
Plugs 1 & 4 seem lean while 2 & 3 are rich.[/ol]
What is my next step, fuel filter, fuel system, fuel injectors? HELP???

 

Swap out the injectors to the bad cylinders and see if it duplicates the problem,sounds like two plugged injectors.Fuel filter,fuel pump would respond to all 4 injectors,if the two are bad you can take them to a injector shop and have the cleaned professionally.
