There is no test procedure I know of that requires adjusting the mixture screw EXCEPT setting the fuel mixture to get the Lambda system set. If the mixture was set and the engine ran fine on that setting then you should not disturb it. Fix what's wrong, you WILL NOT fix the car by twiddling the mixture screw. (That is unless you already fiddled with it and now it is not set correctly!!!!). I say if you can't start the car 3-4 hours after stopping it try the plug swap and see what happens. That will tell us a lot. David Teitelbaum vin 10757 --- In dmcnews@xxxxxxxxxxxxxxx, "bitsyncmater" <david.mckeen@...> wrote: > > That is something I have not tried.
