went thru and replaced any loose vacuum connectors, belt adj ect. The engine poooors pretty good now. RPM's at idle is between 650 and 750.

After all that and a bottle of 91 percent rubbing alcohol, these are the numbers,

HC .34 has to be less than 1.60

CO 2.02 has to be less than 15.00

NOX 1.70 < 2.50

now I have to change out the exhaust man on my 83 300sd.
