anon · 2005-02-03T08:54:13+00:00

hope someone can shed some light on this one,mercedes 190E 2.0 1992 with mechanical injection. it wont start, we can getit running using easy start but it wont idle and the throttle needs to bepumped or held above 2000rpm to keep it running,theres a good spark, all the vacuum pipes are good and not disconnected,there are no leaks anywhere on the inlet manifold etc.we've replaced the fuel pump on advice from mercedes. (thanks guys, £150down the drain)we've checked the relay and relevant fuse behind the battery (which ibelieve is part of the cold start injector?)I'm pretty sure the problem is fuel related as once ive managed to fire itup using easy start (aerosol) it runs great above 2000 rpm, but anythingunder and it dies.any help greatley appreciated.regards.steve UK.

If your mechanic is so great, why are you shopping for parts? He should know where to get a good deal on these. Sure he will double the price, but that's how it works. You gotta pay if you want to play.

Marty, you are absolutley right, herewith I publicly apologize to the Champion spark plug CO, I was incorrect re the quality of their plugs.

Meanwhile I have tracked down the real problem, and it was not ionized air as someone suggested .... although I did follow up on that for a bit. It was the resistor inside the boot that goes over the plug. Now, if anyone has replaced their id their ignition wiring lately, I would love to buy these from them to find maybe a couple of good ones to replace mine. Any help much appreciated

cheers, guenter
