So heres the story...

Over the last year or so i have replaced the idle air valve, injectors, fuel pumps, fuel filter, fuel pump relay, cold start valve on my 190E 2.5 16 valver.

Anyway shes been running great, no problems.

Then i had cause to change the EHA valve. So i bought one, fitted it...fitted new o ring seals aswell.

The car struggled to start. But eventually it did but i really had to prod the accelerator to get it going, above 2.000 revs it was fine.

Anyway it turned out that they gave me the wrong EHA valve, my old one had a different part number.

So i fitted the correct one. Now it really really struggles to start. When it does its as if its running on three cylinders. It then just dies after about 10 seconds. If i try and touch the accelerator it instantly dies.

What gives?

Im a bit baffled.

I have checked the spark plugs, they are new along with the ignition leads.

Any help would be most appreciated.

thanks guys
