Mark, Based on your description here is what I think has happened. As you indicated you probably have a problem in the fuel enrichment circuit. When you re-inserted the Lambda relay one of the female contact blades for the relay may have been pushed down inside the relay socket. To determine if this has happened pull the relay and look down inside the socket and confirm that all the female contacts are visible. You may also have a problem in the idle speed circuit if the engine is idling less than 750 RPM's.

My car runs ok when warmed up except for a lack of power ( it is an automatic) that I am pretty certain is the lambda circuit (it is dead per some professional advice). When cold, it hesitates when you step on the gas until warmed up. I was checking the relays and pulled the Main Fuel relay along with the H.R.W. Timer relay, A/C Illumination relay and the Start Inhibit relay. Put them all back in their proper place and now the car runs terrible. Started it when cold and the car hovered around 500 rpm and every time I stepped on the gas it almost stalled out unless I punched the accelerator (much worse then my usual experience). Any thoughts on how I screwed this up?? I think I should stick to just putting gas in it and leave it at that. Mark [Non-text portions of this message have been removed]
