Maybe the salvage yard sent me the wrong fuel distributor? I plugged off the hole(> on the pic)that goes to what I think should be the Lambda control. I finally found the system pressure settings on my CD of 5.6 bar sytem pressure and set that by adding shims from my old distributor to the valve. Should I send this back and request a distributor from one without lambda. It idles fine in Park but with a load on the engine same story. I can't even drive it. Gas analyzer was also set to 1.5% CO. Help please.
